excel formula, detect building number in address

I have a column with addresses. I need a formula in excel to detect whether this data has a building number in the address line 1. Please see below sample data. I am trying to detect if this is a good address format or not in excel. This will help with my analysis. For example, H street below does not have a building number but 104 Washington Dr does have a building number. How can I build a formula to do this? Thanks!
