Regular expresion

Here's my script

read number
if echo $number | grep "[0-9][^a-zA-Z]"

I want this "if" statement to return true only when numbers without letters is matched.
For example 45 - true, 923 - true, r5 - false, tg/f - false and so on.
In this script even a single digit number like "3" returns false.

Thanks.
