public class TidLUCheckDigit extends IsoIecPure97System
Check digit calculation based on modulus 11 for Luxembourg TIN numbers.

The TID number has 13 digits (9999999999999), the 2 last digits are check digits. The 12 th digit is a check digit calculated on the basis of the algorithm “de Luhn 10”, calculated on the 11 first digits. The 13th digit is a check digit calculated on the basis of the algorithm “de Verhoeff”, calculated on the 11 first digits.
