Is 429 a prime number?

I Dont know if this is for prime's or not but i can remember doing this thing. you add up the numbers of the digit ( 4+2+9=15) Then You see if 15 is a prime then you have the answer. ================================ 429 = 3*11*13. Hence, it is not a prime number. A comment on the first author's response: 37 is a prime number. The sum of 3 and 7 is 10. Ten is not a prime number. Hence the rule does not apply universally. The rule does not apply to 11, 13, ,17, or 19, all known prime numbers, either. I find the related link to be useful. ================================
