Oh I think I understand now what you are asking.
On cell D1 there will only be one of those 'codes' nothing else,
theres no need to check if the value of cell D1 is one of those odd
numbers.
That is done elsewhere.

They are supposed to be code to determine what combination is allowed
between the columns.
It can be anything really, I just thought of using odd numbers. :)
