The digital root (sum of digit) must be divisible by 9,

and

the number formed by the last 4 digits must be divisible by 16.

The second requirement ensures that the number is divisible by 16.

144 is divisible by 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144. To check if a number is divisible by 144, you can first check if it is divisible by 2 (even number), then by 3 (sum of digits divisible by 3), and finally by 16 (last two digits divisible by 4 and the number formed by the last three digits divisible by 8).
