CheckDigits::MBase_002 - compute check digits for blood bags (DE), BZÜ (DE), VAT Registration Number (DE)
use Algorithm::CheckDigits; $bb = CheckDigits('blutbeutel'); if ($bb->is_valid('2761011234567893')) { # do something } $cn = $bb->complete('276101123456789'); # $cn = '2761011234567893' $cd = $bb->checkdigit('2761011234567893'); # $cd = '3' $bn = $bb->basenumber('2761011234567893'); # $bn = '276101123456789';
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,
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.
Returns the basenumber of $number
if $number
has a valid check digit.
Return '' otherwise.
Returns the checkdigit of $number
if $number
has a valid check digit.
Return '' otherwise.
None by default.
