The Luhn mod N algorithm is an extension to the Luhn algorithm (also known as mod 10 algorithm) that allows it to work with sequences of non-numeric characters. ... The reverse operation will provide the reverse mapping. Additional ranges of characters can be dealt with by using conditional statements. This calculator calculates digit sequence checksum using Luhn algorithm (mod 10) and validation digit, the digit to be appended to the digit sequence to make whole sequence checksum equal to zero. German computer scientist Hans Peter Luhn developed the Luhn algorithm in 1954. It calculates simple checksum formula used to validate identification.
