CNAME records cannot coexist with any other records last time IrCOve checked. See section 2.4 from RFC1912[1]

Yes but before going to RFC details one should check the basic spelling and syntax first...

Well it actually goes back to RFC 1034. Unfortunately it wasnrCOt enforced in nameservers at the beginning and is still not enforced by some servers.
3.6.2. Aliases and canonical names
...
The domain system provides such a feature using the canonical name
(CNAME) RR. A CNAME RR identifies its owner name as an alias, and specifies the corresponding canonical name in the RDATA section of the RR. If a CNAME RR is present at a node, no other data should be present; this ensures that the data for a canonical name and its aliases cannot be different. This rule also insures that a cached CNAME can be used without checking with an authoritative server for other RR types.
