NAME
CheckDigits::M43_001 - compute check digits for Code-39SYNOPSIS
use Algorithm::CheckDigits; $c39 = CheckDigits('code_39'); if ($c39->is_valid('AB-123K')) { # do something } $cn = $c39->complete('AB-123'); # $cn = 'AB-123K' $cd = $c39->checkdigit('AB-123K'); # $cd = 'K' $bn = $c39->basenumber('AB-123K'); # $bn = 'AB-123'
DESCRIPTION
ALGORITHM
- 1.
- After replacing all non numeric letters with their respective values, the sum of all numbers is computers
- 2.
- The checkdigit is the sum from step 1 taken modulo 43.
METHODS
- is_valid($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.
