How to check String format?

Question

How can I check if the string contains a real or integer number, space and string?

e.g. StrCheck["156 af"] = true StrCheck["15.6 af"] = true

StrCheck["a 156 af"] = false StrCheck["a 1.56 af"] = false

Thank you!

Your examples are not really conclusive. What are the criteria for the decision? — Yves Klett, Mar 30 '15 at 15:29

f = StringMatchQ[#, NumberString ~~ " " ~~ __] &;

f /@ {"156 af", "15.6 af", "a 156 af", "a 1.56 af"}

{True, True, False, False}
