Exclude certain numbers from range of numbers using Regular expression

Hi Team

Could some one help me with the regular expression, where we can exclude certain numbers in between from a range of numbers.

Presently, ^([1-9][0][0-9])$ is the regular expression that is configured. Now if i want to exclude a few numbers/one number from it, how do i do it.

try to have all the wanted number listed:
[1|5|7]
so you only allow 1, 5, 7 for that field
