Validates the format and check digit of up to 100 identifiers per call, for an agent about to put an IBAN, ISBN, GTIN/EAN/UPC, container number, VIN, ISIN, CUSIP, SEDOL, LEI, IMO number, BIC or Luhn number into a payment, order or record. Each item is {kind, value}; with kind omitted the engine proposes candidate kinds and answers unknown if two kinds both validate. Reports the normalized form (lower case and spaces accepted) and the expected vs actual check digit. It does not check that the identifier exists, is registered or belongs to anyone, and it does not apply national BBAN check digits inside an IBAN.
