Algorithm::LUHN - Calculate the Modulus 10 Double Add Double checksum
This 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 infor...NEILB/Algorithm-LUHN-1.02 - 15 Nov 2015 20:57:42 UTC
Algorithm::LUHN_XS - Very Fast XS Version of the original Algorithm::LUHN
This module is an XS version of the original Perl Module Algorithm::LUHN, which was written by Tim Ayers. It should work exactly the same, only substantially faster. The supplied check_digit() routine is 100% compatible with the pure Perl Algorithm::...KSCHWAB/Algorithm-LUHN_XS-1.08 - 24 Dec 2018 16:25:56 UTC
Algorithm::Damm - Calculate the Damm error correction check digit.
This module implements the Damm algorithm for calculating a check digit. You can find information about the algorithm by searching the web for "Damm ECC". In particular, see the "SEE ALSO" section (below)....MLX/Algorithm-Damm-1.001.002 - 21 Apr 2013 02:18:18 UTC
