You should clarify what type of scam this number is connected to.
Also, if you want to know if the number still works, just search for a VOiP service. There are lots of them. Keep in mind some are paid:
FireRTC, TextNow, Google Hangouts, Skype, X-Lite, are just some of the services wich you can use to call with a spoofed number instead of your actual phone number.
Usually scammers discard a number after a couple of hours. They change the number to refresh the business. It's been 4 hours, so I'm going to risk and say it's not working by now.
