You may be getting "registry" and "registrar" confused.
For a given TLD such as .com, there is only one registRY, in this case
run by Verisign Global Registry services (formerly Network Solutions
Registry).
When you use the domain's registRAR (such as Network Solutions registrar
or OpenSRS) to update the DNS host addresses, it updates the Verisign
registry, and all registrars (and the root servers) will see the new
value. You do not need to update it with each registrar. Each registrar
does not store their own value.
(I should point out that if you transfer a domain that has DNS hosts
associated with it from NSI registrar to another registrar, then update
the DNS host entries, NSI will still show the old IP addresses when you
do a WHOIS on an NSI domain that uses the hosts. This is merely a
cosmetic bug in NSI's WHOIS and other internal systems due to
unbelievable incompetence or malice on their part, and does not affect
the working of the domain or the root server entries, which have the
updated values. There appears to be nothing you can do about this
cosmetic problem, which confuses people. I suspect NSI leaves it this way
because it scares people who have moved away: they can say "if you stayed
with us, this wouldn't happen".)
It generally takes between 12-48 hours for all the root servers to be
updated, just like any DNS change. And since there is a 2-day TTL cache
on the root server records, you have to wait at least 2 days beyond that
before you can even begin to assume that everyone is using only the new
servers. (Note that this applies to .com, .net and .org; other root
server implementations such as .cc and .tv appear to have shorter cached
values and more frequent updates.)
