Nope

Firstly there is no such thing as OCTET defined in ASN.1 - OCTET
STRING is probably what you meant. In any case, and OCTET STRING is
defined as is a string of characters. This means the corrected above
would be a sequence of 5 strings - each string of arbitrary length. I
think what you want is something more like

	VersionNumber ::= OCTET STRING (SIZE (1..5))
 
This says VersionNumber is an OCTET STRING of between 0 and 6
characters long.

Hope this helps.
