NAME¶
CheckDigits::M11_006 - compute check digits for Código 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.
EXPORT¶
None by default.
