group policy setting to restrict which users are allowed to sign in to google chrome

I am trying to setup a group policy for chrome to "restrict which users are allowed to sign in to google chrome". Any ideas what the correct formatting of the string should be for this setting if I need to include multiple domains as in restricting to domains in this list? 

wc.k12.mo.us
maryviller2.com
moval.edu
sps.org

Is this the correct format? *@wc.k12.mo.us|*@sps.org|*@moval.edu|*@maryviller2.com
