How to filter out strings?

[JT0168]

I have columns with V_string type which I need to remove the following using Alteryx workflow: Would appreciate your help on this. 

Characters that start with any number except 0 and has more than 7 characters.

Example:

8046489335

163768034

81307446

1908876001

21369876

20,201,345,202,201

On the other hand, wanted to keep the following in the same column:

PO 0002450000

INV 230450, P.O. 0002356789

1678900

R00034567

Thank you!
