  1. Each number of the RUC is multiplied starting from left to right with 5, 4, 3, 2, 7, 6, 5, 4, 3, 2.

  2. Then sum all the results.

  3. The result has to be divided by 11 (the name of the Module)

  4. After the division, the remaining is subtracted by 11 (11- remaining of the division)

     • If the result is over 0 and less than 10, that's the verifying number we are looking for

     • If the result is 0 or 10, the verifying digit is 1
