NAME
CheckDigits::MXX_004 - compute check digits for VAT RN (AT)
SYNOPSIS
use Algorithm::CheckDigits; $vat = CheckDigits('ustid_at'); if ($vat->is_valid('U13585627')) { # do something } $cn = $vat->complete('U1358562'); # $cn = 'U13585627' $cd = $vat->checkdigit('U13585627'); # $cd = '7' $bn = $vat->basenumber('U13585627'); # $bn = 'U1358562'
DESCRIPTION
ALGORITHM 1. Beginning right all numbers before the check digit are weighted alternatively 1 and 2. 2. The total of the digits of all products is computed and then subtracted from 96. 3. The check digit is the sum of step 3 taken modulo 10. METHODS is_valid($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.
