The last column appears to be literally a checksum - it's the sum of the first 6 bytes after splitting the channel ID into two bytes, ignoring overflow.
ex. 1st row:
(0b11111011 + 0b01101011 + 0b01000100 + 0b00011110 + 0b00001001 + 0b01000001) & 0xff == 0b00010010
I only looked at the first 3 rows though - try checking the others to be sure
