Regex within IF statement in awk

Hello to all,

I have:
Code:
X="string 1-"
Y="-string 2"
Z="string 1-20-string 2"

In the position of the number 20 could be different numbers, but I'm interest only when the number is 15, 20,45 or 70.

I want to include an IF within an awk code with a regex in the following way.

Code:
if(Z!~/X(15|20|45|70)Y/)

but it seems is not working. What is wrong? is possible?

The following way works:
Code:
if(Z!=X15Y && Z!=X20Y && Z!=X45Y && Z!=X70Y)

But I want to reduce the code and with a Regex would be much better.

Thanks in advance.
