Offline validator for a Danish CVR-nummer (8-digit business registration number issued by the Danish Business Authority). Normalizes input to digits only, checks length and computes a modulus-11 checksum using weights 2,7,6,5,4,3,2 on the first 7 digits compared against the 8th check digit. Result is flagged as best-effort since some legacy CVR numbers do not conform to the checksum rule.

Offline validator for South American tax IDs: Argentine CUIT/CUIL (11-digit check digit algorithm), Chilean RUT (mod-11 check digit, 0-9 or K), and Colombian NIT (mod-11 verification digit with DIAN weights). Returns whether the check digit matches and a normalized/formatted value.

Offline structural validator for an Indian CIN (Corporate Identity Number, 21 characters). Parses and checks: listing status letter (L/U), 5-digit NIC industry code, 2-letter state code (against the known MCA state-code list), 4-digit incorporation year (plausible range), 3-letter company-type/ownership code (against a known enum like PLC, PTC, OPC, GOI, NPL, FTC, SGC, ULL, ULT), and 6-digit regis

Offline validator for an Austrian Firmenbuchnummer (FN), the company register number. Normalizes the numeric part (1-6 digits, left-padded to 6 for calculation), computes the modulo-11 check letter using weights 2,1,2,1,2,1 (Luhn-style digit reduction for products >=9 by subtracting 9) and the standard letter table (0=p,1=a,2=b,3=c,4=d,5=e,6=f,7=g,8=h,9=i,10=k), and compares it to the supplied che

Offline validator for a Mexican RFC (Registro Federal de Contribuyentes). Checks the format for persona física (4 letters + 6-digit date + 3-char homoclave) or persona moral (3 letters + 6-digit date + 3-char homoclave), verifies the embedded date is a real calendar date, and returns the parsed birth/incorporation date. Pure string/date logic, no network calls.

Offline validator for a Guatemalan CUI (Código Único de Identificación), the 13-digit national ID number. Parses the 13 digits into an 8-digit correlative, a 1-digit check digit, a 2-digit department code and a 2-digit municipality code, recomputes the check digit using the published weighted mod-11 formula (weights 2-9 over the 8 correlative digits, mod 11, 10→0) and compares it, returning validi

Offline validator for a Romanian CUI (company tax ID). Strips an optional 'RO' prefix, applies weights 7-5-3-2-1-7-3-2 to the digits preceding the check digit (right-to-left), sums the weighted products, multiplies by 10, takes mod 11 (mapping a remainder of 10 to 0), and compares the result to the supplied check digit.

Offline validator for a Swedish Organisationsnummer (company registration number). Normalizes input to 10 digits (accepts XXXXXX-XXXX or plain), checks length/digit-3 validity, and verifies the final check digit using the Luhn (mod 10) algorithm.

Offline validator for an Indian PAN (Permanent Account Number): normalizes input to uppercase, checks the 10-character AAAAA9999A pattern, and validates the 4th character against the known holder-type code enum (P=Individual, C=Company, H=HUF, F=Firm, A=AOP, T=Trust, B=BOI, L=Local Authority, J=Artificial Juridical Person, G=Government). Does not verify the undisclosed final check character.

Offline structural validator for a Vietnamese Enterprise/Tax Code (Mã số thuế, MST). Strips spaces, checks the 10-digit head-office pattern or the 13-character branch pattern (10 digits + '-' + 3-digit sequence). Uses regex only since the official modulus-11 check-digit weight table is not consistently published.

Offline validator for Brazilian CPF (individual) and CNPJ (company) registration numbers. Strips formatting, checks length, rejects known invalid sequences (all same digit), and recomputes the official modulo-11 check digits for both formats.

Answer from TRUSTED sources only (Wikipedia, Wikidata, arXiv, Crossref/DOI, World Bank): returns passages with URL, reliability tier and retrieval time for citation. With synthesize=true you also get an LLM answer that cites the passages and admits when they don't contain the answer.

Human or synthetic? Provenance evidence for a URL: archive first-capture date, domain age, authorship markup, curated source tier, AI disclosures and stylometric signals, aggregated into a calibrated 0-100 human-origin score with every piece of evidence. Add deep=true for an LLM stylometric assessment.

Offline validator/normalizer for a Danish CPR-nummer (personal identification number, format DDMMYY-SSSS). Checks digit count and date-of-birth validity, determines century from the 7th digit per official rules, and derives birth date and gender (last digit odd=male, even=female). Does not rely on the modulus-11 checksum since it has not been guaranteed valid for numbers issued since 2007.

Offline validator for a Czech/Slovak rodné číslo (birth number). Normalizes input to YYMMDD/XXXX or YYMMDDXXX(X), checks the calendar-valid month/day (accounting for the +50 female and +20/70 post-2004 month offsets), and for 10-digit numbers confirms the full digit string (slash removed) is evenly divisible by 11. No network calls.

Offline validator for a Dutch RSIN (Rechtspersonen Samenwerkingsverbanden Informatie Nummer), a 9-digit legal-entity tax identifier. Normalizes input (strips spaces/dots/dashes) and applies the elfproef (mod-11 check): weights 9,8,7,6,5,4,3,2 on the first 8 digits, minus the 9th digit, must be divisible by 11.

Offline validator for a Belgian National Register Number (Rijksregisternummer / Numéro de registre national), format YYMMDDXXXCC. Verifies the two check digits equal 97 minus (first nine digits mod 97), applying the +2,000,000,000 offset for persons born in year 2000 or later, and parses birth date, gender and sequence number.

Offline validator for an Irish PPSN (Personal Public Service Number): checks the 7-digit + 1 check-letter (+ optional trailing 'A' or 'H' modifier letter) format and verifies the check letter using the published mod-23 weighted-sum algorithm (weights 8..2, optional modifier adds 9 or 72). Processes a single PPSN only; no network access or storage.

Offline validator for an Italian Partita IVA (VAT number): verifies the value is 11 numeric digits and recomputes the Luhn-like check digit (digits in odd positions summed as-is, digits in even positions doubled with 9 subtracted if the result exceeds 9, total summed and complemented mod 10) to confirm it matches the 11th digit.
