CheckDigits::M10_011 - compute check digits UPS (US)
use Algorithm::CheckDigits; $ups = CheckDigits('ups'); if ($ups->is_valid('1Z 591580 68 55587736')) { # do something } $cn = $ups->complete('1Z 591580 68 5558773'); # $cn = '1Z 591580 68 55587736' $cd = $ups->checkdigit('1Z 591580 68 55587736'); # $cd = '6' $bn = $ups->basenumber('1Z 591580 68 55587736'); # $bn = '1Z 591580 68 5558773'
Beginning left all numbers are weighted alternatively 1 and 2.
The sum of all products is computed.
The sum of step 3 ist taken modulo 10.
The check digit is the difference between 10 and the number from step 3.
Returns true only if $number consists solely of numbers and the last digit is a valid check digit according to the algorithm given above.
$number
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.
None by default.
