You need to take each charater of your string and then convert it to in ascii and check the values of it.

You can get the logic in one of the post how to break the string into the characters and converting it into the ascii...

Since you already know that the Seq() function returns the ASCII code associated with any character, the answer should be obvious. You need to create a routine that checks each character individually.
