NAME

CheckDigits - Perl extension to generate and test check digits

SYNOPSIS

  use Algorithm::CheckDigits;

  $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'


  Algorithm::CheckDigits->method_list();

ABSTRACT

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).
