Extracting A Set of Numbers from a String

[AlteryxUserFL]

I need to extract a number form a long string with text and numbers. Basically, I need to extract the first number that starts with 73. Would Regex be best? Please see below for an example. 

Start:

" 19071017 TOTAL BUDGE OLD PO 739003018  40373,PROTOCOL NO 3222220140106 CO5 THIS PROPOS 06 CO6 THIS AMENDMENT IS SUBJECT TO THE AND CONDITIONS OF THE MASTER AGREEMENT CONTRACT NO XYZ220 ENTERED INTO BY AN."

Output: "739003018"

Hi @AlteryxUserFL 

Yes, you can use regex parse for this

.*(73\d+).*
