(1x5) + (3x16) + (1x15) + (3x14) = 110
Again, a value is obtained that is a multiple of 10, validating this row checksum.
The X at the end of the line is a mod 36 block checksum with 137 weighting. It
protects all the characters in the template, including the first line. Calculating its
sum working backwards from the block checksum and using the 137 weighting
scheme:

(1x34) + (3x5) + (7x16) + (1x15) + (3x14) + (7x6) + (1x13) + (3x12) + (7x11) + (1x10) = 396
The resulting sum is a multiple of 36, so the block checksum has been vali-
dated.
