It seems that the folks at scicrunch.org have changed the webpage that I was scraping to determine if the RRID was valid and also they discontinued their previous webpage.
So, Michael Caldwell has researched this and has found that there is a new interface which returns json:
https://scicrunch.org/resolver/.json
Which could be used in the validation portion of the code. If you remove the .json from the end of the URL you get a webpage describing the RRID which could be used in the frontend link for the RRID.
