What I did for something similar was to use aqString.Trim to get all the spaces out of the string and then loop through it a character at a time looking for a digit. That will get you the position of the first digit. Then you can use aqString.Substring to get the 10 digits.
I never found a way to use the regular expressions for this. Looks like you can use them to compare but not for string manipulation.
