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
