Looking for some confirmation that DT's CRC calculation routine will work with CRC-8.

This is two typical samples of what I have incomming from a Fine Offset WH2081 weather station transmitter.
FF AD 42 CB 16 05 06 00 6C 0E 87
FF AD 42 CC 16 05 08 00 6C 0C 0D

FF is a preamble, and the last byte is CRC-8 using the polynomial x^8 + x^5 + x^4 + 1 (which I think becomes the constant $131 for calculations).
The middle 9 bytes are data, and used for the CRC byte sent by the TX.

Do I have it right that DT's code could be used directly if the CRC_Len and CRC_poly constants are changed as below ?

CRC VAR WORD
CRC_IN VAR BYTE
Idx VAR BYTE
CRC_Len CON 8
CRC_Poly CON $131 ; x^8 + x^5 + x^4 + 1

;-----CRC-16 -----------------------------------------------------
CRC16:
CRC.HighByte = CRC.HighByte ^ CRC_IN
FOR Idx = 0 to 7
IF CRC.0(CRC_Len-1) THEN
CRC = (CRC << 1) ^ CRC_Poly
ELSE
CRC = CRC << 1
ENDIF
NEXT Idx
RETURN

If so, is it just a matter of setting the CRC_IN byte to each value of the nine data bytes in turn while looping through CRC16: each time, the wanted result being the value of CRC after the ninth loop ?
Or is there stuff to be done after each result of subroutine CRC16 ?

Thanks if anyone can confirm that for me before I try to hack my receiver code to pieces.
