Code() doesn't really need Left().

Besides, can't get your formula to accept:
A12345

This works based on the following conditions:

Length must be 6 characters
The 1st character must be upper case A-Z
Chars 2 through 6 must be numbers 0-9

=AND(LEN(A1)=6,CODE(LEFT(A1))=65,CODE(LEFT(A1))<= 90,COUNT(-MID(A1,ROW(INDIRECT("2:6")),1))=5)
