CheckDigits::M89_001 - compute check digits for VAT Registration Number (LU)
SYNOPSIS
use Algorithm::CheckDigits;
$ustid = CheckDigits('ustid_lu');
if ($ustid->is_valid('13669580')) {
# do something
}
$cn = $ustid->complete('136695');
# $cn = '13669580'
$cd = $ustid->checkdigit('13669580');
# $cd = '80'
$bn = $ustid->basenumber('13669580');
# $bn = '136695'
DESCRIPTION
ALGORITHM
1. The checksum is the whole number taken modulo 89.
METHODS
is_valid($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.

CheckDigits::M11_008 - compute check digits for VAT Registration Number (DK)
SYNOPSIS
use Algorithm::CheckDigits;
$ustid = CheckDigits('ustid_dk');
if ($ustid->is_valid('13585628')) {
# do something
}
$cn = $ustid->complete('1358562');
# $cn = '13585628'
$cd = $ustid->checkdigit('13585628');
# $cd = '8'
$bn = $ustid->basenumber('13585628');
# $bn = '1358562';
DESCRIPTION
ALGORITHM
1. Beginning left every digit is weighted with 2, 7, 6, 5, 4, 3, 2, 1
2. The weighted digits are added.
3. The sum from step 2 is taken modulo 11.
4. The number is valid if the sum from step 3 is zero(0).
METHODS
is_valid($number)
Returns true only if $number consists solely of numbers and hyphens and the two digits in the middle are valid check digits according
to the algorithm given above.
Returns false otherwise,
complete($number)
The check digit for $number is computed and inserted into the middle 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 '' if $number is valid.
Return undef otherwise.
EXPORT
None by default.
