public class TidHUCheckDigit extends Modulus11iLeftCheckDigit
Check digit calculation based on modulus 11 and weighs based on the digit position.

Digits are weighted based by their position, from left to right with the first digit being weighted 1, the second 2 and so on. Check digit cannot be 10.

This module is used to calculate Hungarian TIN check digits „adóazonosító jel“ for natural persons and "Adószám" for companies and organisations. See Wikipedia (hu) and Adószám (hu) for more details.
