Validate the pattern in string

[AOD]

Hi All,

Need help in validating a specific string pattern in the field.  Can you please advice on how can this be achieved in DAX? Thanks.

Rule is as below

1st - Letter        
2nd - Letter/ digit
3rd - Space/ digit
4th - Space/ digit
5th - Space/ digit/ Letter              
6th - Letter/ digit
7th – Letter

@AOD , where is the pattern missing?

In power query, we can use Text.Contains to search
