Formulas cannot clear cells, but for your intents you could try a formula
col, apply an autofilter on it, then manually select/clear the filtered rows.

Try this play on a spare copy of your book

It presumes that the Reg. Nos in col A in both Sheet1 and Sheet2 alone
suffices to establish the uniqueness of the data

Insert a new col C in Sheet1
Put in C2:
=IF(A2="","",ISNUMBER(MATCH(A2,Sheet2!A:A,0)))
Copy C2 down to the last row of data in col A

Apply autofilter on col C, filter out: TRUE

The filtered rows will be the result lines that you seek, ie lines where Reg
Nos in col A is found in Sheet2's col A. You could then easily select the
filtered data in the cols to the right, and clear these with the Delete key.
