NAME
CheckDigits::M11_015 - compute check digits for ESR5 (CH)SYNOPSIS
use Algorithm::CheckDigits; $ustid = CheckDigits('esr5_ch'); if ($ustid->is_valid('050001000012000 241170032660178 10304')) { # do something } $cn = $ustid->complete('0001000012000 241170032660178 10304'); # $cn = '050001000012000 241170032660178 10304' $cd = $ustid->checkdigit('0001000012000 241170032660178 10304'); # $cd = '05' $bn = $ustid->basenumber('050001000012000 241170032660178 10304'); # $bn = '0001000012000 241170032660178 10304';
DESCRIPTION
ALGORITHM
- 1.
- Beginning right all digits are weighted with the repeating sequence 2, 3, 4, 5, 6, 7.
- 2.
- The weighted digits are added.
- 3.
- The sum from step 2 is taken modulo 11.
- 4.
- The checkdigit is 11 minus the sum from step 3. If the difference is 11, the checkdigit is 00.
METHODS
- is_valid($number)
- Returns true only if $number consists solely of numbers (with or without space between them) and the first two digits are valid check digits according to the algorithm given above.
Returns false otherwise,
- complete($number)
- The check digit for $number is computed and inserted before the $number.
Returns the complete number with check digit or '' if $number does not consist solely of digits, spaces.
- basenumber($number)
- Returns the basenumber of $number if $number has a valid check digit.
Return '' otherwise.
- checkdigit($number)
- Returns the check digits of $number if $number has valid check digits.
Return '' otherwise.
