"No, this data sheet is for checksum."

Which one?

The Dalla App Note 27 that I cited definitely covers CRC (Cyclic Redundancy Checks); not just checksums.

Specifically, the 8-bit Dallas One-Wire (DOW) CRC, polynomial x^8+x^5+x^4+1
and their 16-bit data CRC, polynomial x^16+x^15+x^2+1

"CRC ... Is more complicated but more powerful in error detection [than checksum]."

Absolutely.
The Dallas App Note also tells you precisely what errors their CRCs will detect.
