NAME
CheckDigits::M11_006 - compute check digits for CA~Xdigo de Cuenta Corriente (ES)SYNOPSIS
use Algorithm::CheckDigits; $ccc = CheckDigits('ccc_es'); if ($ccc->is_valid('2420-0730-27-0050103552')) { # do something } $cn = $ccc->complete('2420-0730- -0050103552'); # $cn = '2420-0730-27-0050103552' $cd = $ccc->checkdigit('2420-0730-27-0050103552'); # $cd = '27' $bn = $ccc->basenumber('2420-0730-27-0050103552'); # $bn = '2420-0730- -0050103552';
DESCRIPTION
ALGORITHM
- 1.
- Beginning right all digits are weighted 6,3,7,9,10,5,8,4,2,1.
- 2.
- The weighted digits are added.
- 3.
- The sum of step 2 is taken modulo 11.
- 4.
- The checkdigit is 11 minus the sum from step 3.
If the difference is 10, the checkdigit is 1.
If the difference is 11, the checkdigit is 0.
METHODS
- is_valid($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 the check digits of $number if $number has valid check digits.
Return '' otherwise.
