I have tried to first calculate the value of 2^n and then adding one to it and then apply the logic of prime number.

CheckDigits::M11_015(3pm) User Contributed Perl Documentation CheckDigits::M11_015(3pm)NAME
CheckDigits::M11_015 - compute check digits for ESR5 (CH)
SYNOPSIS
use Algorithm::CheckDigits;
$ustid = CheckDigits('esr5_ch');
if ($ustid->is_valid('123456786')) {
# do something
}
$cn = $ustid->complete('12345678');
# $cn = '123456786'
$cd = $ustid->checkdigit('123456786');
# $cd = '6'
$bn = $ustid->basenumber('123456786');
# $bn = '12345678';
DESCRIPTION
ALGORITHM
1. Beginning left every digit is weighted with 7,9,10,5,8,4,2.
2. The weighted digits are added.
3. The sum from step 2 is taken modulo 11.
4. The checkdigit is 11 minus the sum from step 3. Is the difference 10, the number won't be taken. If the difference is 11, the
checkdigit is 0.
METHODS
is_valid($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.
