F9D

The polynomial for the VAN CRC is

x^{15 + x}11 + x^{10 + x}9 + x^{8 + x}7 + x^{4 + x}3 + x^2

To translate it to a hexadecimal poly value, you will need to take a 15 bit value and write a one in each interesting bit position.

The 15 bits are numbered from 14 to 0 . The leftmost (MSB) bit represents x^{14 (x}15 is implicit) and the rightmost x^0 (which must always be set in any CRC poly, so it’s often not mentioned in the formula).

The result is:

000111110011101

or

0xF9D
