/**
 * <p>
 * Implements Dutch Post KIX Code as used by Royal Dutch TPG Post (Netherlands).
 *
 * <p>
 * The input data can consist of digits 0-9 and characters A-Z, and should be 11 characters in
 * length. No check digit is added.
 *
 * <p>
 * KIX Code is the same as RM4SCC, but without the check digit.
