For each of the three encoded numerals, the most significant digit is on the left and the least significant digit is on the right; for example, the film class is a seven-bit number encoded in positions 2 through 8; position 8 is the least significant digit, and position 2 is the most significant digit. In this example, the binary number encoded (1001111) for the film class is equal to 79 (base-10). The parity bit is set or left blank to ensure the total number of "1" bits in positions 1 through 12 plus the parity bit is even. In this example, there are nine "1" bits in positions 1 through 12, so the parity bit is set.
