NAME

       CheckDigits::M11_011 - compute check digits for VAT Registration Number (NL)

SYNOPSIS

	 use Algorithm::CheckDigits;

	 $ustid = CheckDigits('ustid_nl');

	 if ($ustid->is_valid('123456782')) {
	       # do something
	 }
	 if ($ustid->is_valid('123456782B04')) {
	       # do something
	 }

	 $cn = $ustid->complete('12345678');
	 # $cn = '123456782'
	 $cn = $ustid->complete('12345678.B04');
	 # $cn = '123456782B04'

	 $cd = $ustid->checkdigit('123456782');
	 # $cd = '2'
	 $cd = $ustid->checkdigit('123456782B04');
	 # $cd = '2'

	 $bn = $ustid->basenumber('123456782');
	 # $bn = '12345678';
	 $bn = $ustid->basenumber('123456782B04');
	 # $bn = '12345678.B04';

DESCRIPTION

       This VATRN has 12 "digits", the third last must be a B, the fourth last is the checkdigit. I don't know anything about the meaning of the
       last two digits.

       You may use the whole VATRN or only the first eight digits to compute the checkdigit with this module.

   ALGORITHM
       1.  Beginning right with the digit before the checkdigit all digits are weighted with their position. I.e. the digit before the checkdigit
	   is multiplied with 2, the next with 3 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 10, the number is discarded.

   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::M10_002 - compute check digits for CINS (US), SIREN (FR), SIRET (FR)

SYNOPSIS

	 use Algorithm::CheckDigits;

	 $siret = CheckDigits('siret');

	 if ($siret->is_valid('73282932000074')) {
	       # do something
	 }

	 $cn = $siret->complete('7328293200007');
	 # $cn = '73282932000074'

	 $cd = $siret->checkdigit('73282932000074');
	 # $cd = '4'

	 $bn = $siret->basenumber('73282932000074');
	 # $bn = '7328293200007'

DESCRIPTION

   ALGORITHM
       1.  Beginning right all numbers are weighted alternatively 1 and 2.

       2.  The total of the digits of all products is computed.

       3.  The sum of step 3 ist taken modulo 10.

       4.  The check digit is the difference between 10 and the number from step 3 taken modulo 10.

   METHODS
       is_valid($number)
	   Returns true only if $number consists solely of numbers and the last digit is a valid check digit according to the algorithm given
	   above.

	   Returns false otherwise,

       complete($number)
	   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.

       basenumber($number)
	   Returns the basenumber of $number if $number has a valid check digit.

	   Return '' otherwise.

       checkdigit($number)
	   Returns the checkdigit of $number if $number has a valid check digit.

	   Return '' otherwise.

   EXPORT
       None by default.
