NAME
CheckDigits::M97_001 - compute check digits for VAT Registration Number (BE)SYNOPSIS
use Algorithm::CheckDigits; $ustid = CheckDigits('ustid_be'); if ($ustid->is_valid('136695962')) { # do something } $cn = $ustid->complete('1366959'); # $cn = '136695962' $cd = $ustid->checkdigit('136695962'); # $cd = '62' $bn = $ustid->basenumber('136695962'); # $bn = '1366959'
DESCRIPTION
ALGORITHM
- 1.
- The whole number (without checksum) is taken modulo 97.
- 2.
- The checksum is difference of the remainder from step 1 to 97.
METHODS
- is_valid($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 checkdigits of $number if $number has a valid check digit.
Return '' otherwise.
