Question Grep -v (inverse matching)

I am totally unexperienced in writing scripts of any kind.
I am working on Mac OS X and would like to run a shell script to find files in a directory that do not conform to a specific naming convention and print to a text file in the same directory.

For example, I have a folder called ScriptTest.
In this folder there are 6 jpg images that must all follow this naming convention:
6 digits(0-9), an underscore, 3 digits(0-9), an underscore, 1 digit(1-4) (ex. 1234567_123_1).
I need to output the names of the files that do not conform to this naming convention, to a text file in the same directory.

I've searched many different forums, but all of the samples I find, either don't produce the results I need, or fail altogether.
Most have used a combination of find or ls used in conjunction with grep and xargs. I still have yet to get one to work...

I do like to research and try to figure things out on my own, but I'm at a dead end here. Any help, would be greatly appreciated!

RMF(1)								     [nmh-1.5]								    RMF(1)

NAME
rmf - remove an nmh folder SYNOPSIS
rmf [+folder] [-interactive | -nointeractive] [-version] [-help] DESCRIPTION
Rmf removes all of the messages (files) within the specified (or default) folder, and then removes the folder (directory) itself. If there are any files within the folder which are not a part of nmh, they will not be removed, and an error will be produced. If the folder is given explicitly or the -nointeractive option is given, then the folder will be removed without confirmation. Otherwise, the user will be asked for confirmation. If rmf can't find the current folder, for some reason, the folder to be removed defaults to `+inbox' (unless overridden by user's profile entry "Inbox") with confirmation. If the folder being removed is a subfolder, the parent folder will become the new current folder, and rmf will produce a message telling the user this has happened. This provides an easy mechanism for selecting a set of messages, operating on the list, then removing the list and returning to the current folder from which the list was extracted. If rmf s used on a read-only folder, it will delete all the (private) sequences (i.e., "atr-seq-folder" entries) for this folder from your context without affecting the folder itself. Rmf irreversibly deletes messages that don't have other links, so use it with caution. FILES
$HOME/.mh_profile The user profile PROFILE COMPONENTS
Path: To determine the user's nmh directory Current-Folder: To find the default current folder Inbox: To find the default inbox SEE ALSO
rmm(1) DEFAULTS
`+folder' defaults to the current folder, usually with confirmation `-interactive' if +folder' not given, `-nointeractive' otherwise CONTEXT
Rmf will set the current folder to the parent folder if a subfolder is removed; or if the current folder is removed, it will make "inbox" current. Otherwise, it doesn't change the current folder or message. BUGS
Although intuitively one would suspect that rmf works recursively, it does not. Hence if you have a sub-folder within a folder, in order to rmf the parent, you must first rmf each of the children. MH.6.8 11 June 2012 RMF(1)
