Another choice, if you see the following byte patterns, no conversion is needed
for CAN to NON-CAN , each 4 bits in hex is also the mirror of the other,
eg 18 = 0001 1000, 66 = 0110 0110, A5 = 1010 0101
00, 18, 24, 3C, 42, 5A, 66, 7E, 81, 99, A5, BD, C3, DB, E7, FF

Keep it simple...
CANONICAL - NON-CANONICAL
quick converter :
Ethernet MAC Addresses (canonical format)
0 1 2 3 4 5 6 7 8 9 A B C D E F becomes
0 8 4 C 2 A 6 E 1 9 5 D 3 B 7 F
Token Ring Address (non-canonical format)
Here is an example on Ethernet according
to the above rule:
1. Ethernet MAC Addresses (canonical format)
0200.4556.1140
2. Intermediate step, flip the bits (take it 2 characters at a time, reverse th
em and then you get step3)
0400.2AA6.8820
3. Final Token Ring Address (non-canonical format)
4000.A26A.8802
