C luhn algorithm
Web4. I was able to find all kinds of examples that demonstrate how to validate a Luhn Checksum but very few that actually generated the check digit. Here is my attempt in base 10, based on the validation examples found at Wikipedia and Rosetta Code: /// WebThis module calculates the Modulus 10 Double Add Double checksum, also known as the LUHN Formula. This algorithm is used to verify credit card numbers and Standard & Poor's security identifiers such as CUSIP's and CSIN's. You can find plenty of information about the algorithm by searching the web for "modulus 10 double add double".
