Mark a row if it doesn't match the row above it on multiple criteria

Is there a formula that I could put in column f that will mark a cell only if all cells in the adjacent row don't match all of the cells in the row above it?

Basically If a2,b2,c2,d2, and e2 dont match a1,b1,c1,d1, and e1 then I would like to put any sort of mark into cell f2.

Thanks!

In F2, try:

=SUMPRODUCT(--(A1:E1=A2:E2))=COLUMNS(A2:E2)

will return TRUE if all cells match, else it FALSE

Only to mark it if no match, you could try:

=REPT("No match",SUMPRODUCT(--(A1:E1=A2:E2))<COLUMNS(A2:E2))

or,

=IF(SUMPRODUCT(--(A1:E1=A2:E2))<COLUMNS(A2:E2),"No match","Match")

and change the text string within inverted commas as needed.
