Check the rightmost character - if it's a comma, set the string to a substring of the original, with length -1.

Trimming the string ensures that spaces after the trailing comma don't interfere with this method.

<cfset myStr = "hello, goodbye,">
<cfset myStr = trim(myStr)>

<cfif right(myStr, 1) is ",">
    <cfset myStr = left(myStr, len(myStr)-1)>
</cfif>
