It is still valid. The reference in question in RFC 4645 is:
--
4. Omitted Code Elements
The following code elements from [UN_M.49] were not associated with
[ISO3166-1] alpha-2 code elements. Consequently, they were not
assigned as subtags in the initial Language Subtag Registry, but were
valid candidates for registration as region subtags, using the
process in [RFC4646]:
830 Channel Islands
831 Guernsey
832 Jersey
833 Isle of Man
The last three became ineligible for registration in April, 2006,
when the [ISO3166-1] code elements GG, JE, and IM were assigned as
region subtags.

Thus, '830' is still valid for registration. At one time, the rules were even more permissive (hence this text). Incidentally, this reference is why RFC 4645 is still a normative reference in draft-4646bis.
