I have the following Greek Sentence which I want to process using OpenAI and get a value:

Α. ΔΥΝ. 36111 Ημερ. Εγγρ.

I tried the following prompt configuration:

The number might be located next to the phrase Α. ΔΥΝ. or before the phrase Ημερ. Εγγρ. Please return the extracted number even if it is not in a valid format.

But I can’t get the value. How I can get the value?

Can I user other expresisons?
