About the Luxembourg IBAN
An IBAN (International Bank Account Number) for Luxembourg has 20 characters: the country code LU, a 2-digit check number, a 3-character bank code and the account number. The check digits are calculated with the ISO 7064 MOD-97 algorithm, so a single typo makes the IBAN invalid — which is what this tool checks.
