Character classes have their own rules. I don't recommend using them
unless you know precisely what you are doing. I like Brian's regex of
"(\*|\d{6})"

In brackets you have interesting things, like dashes not always being
dashes and a leading caret meaning negation.

[^A-Z]  <== what does this mean? ;)

In any case, check the regular expressions page on the wiki for more
online resources.
