Algorithm::CheckDigits - Perl extension to generate and test check digits
perl -MAlgorithm::CheckDigits -e Algorithm::CheckDigits::print_methods
or
use Algorithm::CheckDigits; @ml = Algorithm::CheckDigits->method_list(); $isbn = CheckDigits('ISBN'); if ($isbn->is_valid('3-930673-48-7')) { # do something } $cn = $isbn->complete('3-930673-48'); # $cn = '3-930673-48-7' $cd = $isbn->checkdigit('3-930673-48-7'); # $cd = '7' $bn = $isbn->basenumber('3-930673-48-7'); # $bn = '3-930673-48'
This module provides a number of methods to test and generate check digits. For more information have a look at the web site www.pruefziffernberechnung.de (german).
Returns an object of an appropriate Algorithm::CheckDigits class for the given algorithm.
Dies with an error message if called with an unknown algorithm.
See below for the available algorithms. Every object understands the following methods:
Returns true or false if $number contains/contains no valid check digit.
$number
Returns a string representation of $number completed with the appropriate check digit.
Extracts the check digit from $number if $number contains a valid check digit.
Extracts the basenumber from $number if $number contains a valid check digit.
Returns a list of known methods for check digit computation.
You may use the following to find out which methods your version of Algorithm::CheckDigits provides and where to look for further information.
At the moment these methods to compute check digits are provided: (vatrn - VAT Return Number, in german ustid UmsatzSTeuer-ID)

Petri Oksanen made me aware that CheckDigits('IMEI') would invoke no test at all since there was no entry for this in the methods hash.
