0 or 1 + MMMMM-00005 + check digit: 5 = P 6: MMMMM6: 0 or 1 + MMMMM-00006 + check digit: 6 = P 7: MMMMM7: 0 or 1 + MMMMM-00007 + check digit: 7 = P 8: MMMMM8: 0 or 1 + MMMMM-00008 + check digit: 8 = P 9: MMMMM9: 0 or 1 + MMMMM-00009 + check digit: 9 = P
However, generally they are considerably slower (typically by a factor 2–10) than fast, non-cryptographic random number generators. These include: Stream ciphers. Popular choices are Salsa20 or ChaCha (often with the number of rounds reduced to 8 for speed), ISAAC, HC-128 and RC4. Block ciphers in counter mode.

The CSC is used as a security feature for card not present transactions, where a personal identification number (PIN) cannot be manually entered by the ...
For example, squaring the number "1111" yields "1234321", which can be written as "01234321", an 8-digit number being the square of a 4-digit number. This gives "2343" as the "random" number. Repeating this procedure gives "4896" as the next result, and so on. Von Neumann used 10 digit numbers, but the process was the same.
