NAME

       CheckDigits::M11_006 - compute check digits for Codigo 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.

NAME

       CheckDigits::M11_013 - compute check digits for VAT Registration Number (GR)

SYNOPSIS

	 use Algorithm::CheckDigits;

	 $ustid = CheckDigits('ustid_gr');

	 if ($ustid->is_valid('123456783')) {
	       # do something
	 }

	 $cn = $ustid->complete('12345678');
	 # $cn = '123456783'

	 $cd = $ustid->checkdigit('123456783');
	 # $cd = '3'

	 $bn = $ustid->basenumber('123456783');
	 # $bn = '12345678';

DESCRIPTION

   ALGORITHM
       1.  Beginning right with the digit before the checkdigit all digits are weighted with 2 ** position. I. e. the last digit is multiplied
	   with 2, the next with 4, then 8 and so on.

       2.  The weighted digits are added.

       3.  The sum from step 2 is taken modulo 11.

       4.  If the sum from step 3 is greater than 9, the check sum is 0 else it is the sum itself.

   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.
