Basically what I want to do is something like this. Ex.
MY LIST
89945789
35468879
10125468
55546871
11123458
52468748
64310250
02584687

And from that list, I want to take out
10125468
11123458
64310250
89945789

I know I could find and replace, just replace with "", but I would have to use a script to this automatically. Is there a formula or some other way to do this?
