Mod10

A simple gem to generate mod_10 check digits and check if integers are mod10 valid.

Add this line to your application's Gemfile:

gem 'mod_10'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mod_10

Include the Mod10 module to make the following two methods available

• generate_check_digit(value) Which returns an integer value for the mod10 check digit of a string or integer. Note: If the value is 0, then the argument was already mod10 valid.

• is_mod10?(value) Returns true or false for the tested value is it is or isn't mod10 valid.
