algorithm::checkdigits::m11_017
CheckDigits::M11_017(3pm) User Contributed Perl Documentation CheckDigits::M11_017(3pm)
NAME
CheckDigits::M11_017 - compute check digits for EC-No, EINECS, ELINCS
SYNOPSIS
use Algorithm::CheckDigits;
$ecno = CheckDigits('ecno');
if ($ecno->is_valid('200-236-6')) {
# do something
}
$cn = $ecno->complete('200-236-');
# $cn = '200-236-6'
$cd = $ecno->checkdigit('200-236-6');
# $cd = '6'
$bn = $ecno->basenumber('200-236-6');
# $bn = '200-236-'
DESCRIPTION
ALGORITHM
1. From left to right all digits are multiplied with their position in the sequence.
2. The sum of all products is computed.
3. The sum of step 2 is taken modulo 11.
The checkdigit is the last digit of the result.
METHODS
is_valid($number)
Returns true only if $number consists solely of numbers and the last digit is a valid check digit according to the algorithm given
above.
Returns false otherwise,
complete($number)
The check digit for $number is computed and concatenated to the end of $number.
Returns the complete number with check digit or '' if $number does not consist solely of digits and spaces.
basenumber($number)
Returns the basenumber of $number if $number has a valid check digit.
Return '' otherwise.
checkdigit($number)
Returns the checkdigit of $number if $number has a valid check digit.
Return '' otherwise.
EXPORT
None by default.
