Employer Identification Number (EIN) Regex

We are trying to create a new policy to detect Employer Identification Number (EIN) in MCAS. I'm very new to Regex so I need some help. We've tried the below regex and MCAS is showing me an error of: Capturing parenthesis not allowed in regular expression. Does anyone know how to convert the below regex to something without the capturing parentheses? Thanks!


([07][1-7]|1[0-6]|2[0-7]|[35][0-9]|[468][0-8]|9[0-589])-?\d{7}
