A number N is divisible by 3 or 9 if the sum of its digits is divisible by 3 or 9.

Consider 392.

Here, 3 + 9 + 2 =14 which is neither divisible by 3 or 9 . But since 392 is an even number, it is divisible by 2. In 392, the last two digits are 92, which is divisible by 4. Hence the number is also divisible by 4.
