put the list of domains in a file, and do:

for domain in `cat filename`
do
  dig $domain soa @<serverIP> +norec
done

and confirm that it prints correct SOA records with the "aa" flag set 
for all of them.  This script can be improved on by piping the dig 
output to some greps that check the output.
