Find Addresses Without Street Number

I have an address list of 64,000 entries that I want to geo-code (the geo-coding isn't the problem...). A large % of addresses don't have street numbers and this just gives a general position based on the Post/ Zip code which isn't accurate enough - it needs to have an actual street number. I want to extract all of the addresses without a street number so I can cross check them with something else (not an Excel problem). Trouble is some of the street numbers are embedded in a string - might be a multiple NOT problem. Attached a sample file...
