NAME
CheckDigits::M11_016 - compute check digits vor VAT Registration Number (PL)SYNOPSIS
use Algorithm::CheckDigits; $nip = CheckDigits('nip'); if ($nip->is_valid('8567346215')) { # do something } $cn = $nip->complete('856734621'); # $cn = '8567346215' $cd = $nip->checkdigit('856734621'); # $cd = '5' $bn = $nip->basenumber('8567346215'); # $bn = '856734621';
DESCRIPTION
ALGORITHM
- 1.
- Beginning left every digit is weighted with 6, 5, 7, 2, 3, 4, 5, 6, 7
- 2.
- The weighted digits are added.
- 3.
- The sum from step 2 is taken modulo 11.
- 4.
- The checkdigit is 11 minus the sum from step 3. Is the difference 10, the number won't be taken. If the difference is 11, the checkdigit is 0.
METHODS
- is_valid($number)
- Returns true only if $number consists solely of numbers and the rightmost digit is a valid check digit according to the algorithm given above.
Returns false otherwise,
- complete($number)
- The check digit for $number is computed and appended to the end of $number.
Returns the complete number with check digit or '' if $number does not consist solely of digits, hyphens and spaces.
- basenumber($number)
- Returns the basenumber of $number if $number has a valid check digit.
Return '' otherwise.
- checkdigit($number)
- Returns the check digits of $number if $number has valid check digits.
Return '' otherwise.
