Can you please confirm that this Regexp does the need

Question

Hello,
I am using this Regexp to make sure that the value:
contains only numbers
Does not start with zeors
In case it starts with 971, then 971 will be deleted
I am using this Regexp:
select regexp_replace ( trim (leading 0 from regexp_replace (' 00097100 32423 971 234 fs dsaf ', '[^[:digit:]]' ,'')), '^971{1}*', '' )from dual I already tested it, it looks fine, but since it is sensitive, would like to get confirmation from experts ..
Regards,
Fateh
