Summary: It consists of four groups of 4 bytes each, separated by three '-' bytes (0x2D).
Each of the 16 checked bytes must be a multiple of its corresponding divisor.
The divisors per group are:
Group 1 (bytes 0-3): 2, 3, 5, 8
Group 2 (bytes 5-8): 5, 7, 12, 19
Group 3 (bytes 10-13): 11, 15, 26, 41
Group 4 (bytes 15-18): 23, 31, 54, 85
Bytes 4, 9, 14 must be exactly 0x2D ('-').
