Conventional Encryption Keys, 5.3

I can create a conventional encryption key using S2K by itself on a
passphrase, but I can also encrypt a conventional key using a S2K on a
passphrase.

In the section beginning:

"The decryption result consists of a one-octet algorithm..."

Shouldn't there also be a two-octet checksum after the random key material
(to be identical to what is public-key encrypted)?
