Ariel Code

The Ariel Code is a series of 14 numbers used to identify Ariel's friends, either a user or a character. Ariel Code was introduced in 14 July 2004 in order to facilitate in character sorting.

Structure
The Ariel Code will be structured as NNN NNN NNN NNN NN where N is a numeric digit.

The spaces do act as separators; however, the last two digits are an error-detecting code to check integrity and structure to allow the catch of single-digit and transposition errors.

Checksum calculation
The first check digit is calculated with the weighting of 13 13 13 13 13 13 while the second check digit is calculated with the weighting of 371 371 371 371. Both checksum algorithms, use 10 modular arithmetic.
