CheckDigits::M23_001(3User Contributed Perl DocumentatiCheckDigits::M23_001(3)NAMECheckDigits::M23_001 - compute check digits for DNI (ES)
SYNOPSIS
use Algorithm::CheckDigits;
$dni = CheckDigits('dni_es');
if ($dni->is_valid('54362315K')) {
# do something
}
$cn = $dni->complete('54362315');
# $cn = '54362315K'
$cd = $dni->checkdigit('54362315K');
# $cd = 'K'
$bn = $dni->basenumber('54362315K');
# $bn = '54362315'
DESCRIPTION
ALGORITHM
1. The checkdigit is the whole number taken modulo 23 and coded
according to a keytable.
METHODS
is_valid($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.
