how to compare data-group values

I am running v11.3 and below is my data-group. I would like to compare my input value ie amit.amit.com with data-group values ie amit.amit.com.au and abcd.abc.com.au and if match is found then do some action otherwise reject

    ltm data-group internal /prt-a/testssl-ma {
    records {
        amit.amit.com.au { }
        abcd.abc.com.au { }
    }
    type string
}

Is below irule will provide "abcd.abc.com.au" ??

when HTTP_REQUEST {
    set compare_val abcd.abc.com.au
    log local0.error "[class match -value $compare_val equals testssl-ma]"
}
