1. Maybe Vim doesn't get the Ctrl-Right combination. To determine if
that is the case, put Vim in Insert mode then hit Ctrl-V (or Ctrl-Q if
your Ctrl-V is remapped to the paste operation) followed by Ctrl-Right.
If nothing appears in the buffer (and, assuming that you have 'showcmd'
on, ^V remains displayed near bottom right of the Vim screen), then Vim
doesn't get the Ctrl-Right combo and there's nothing to be done, other
than selecting a different {lhs} for your mapping, or using gvim, which
should recognise the keystroke correctly.

2. Maybe Vim gets the Ctrl-Right but sees it as no different than
something else. Still in Insert mode, hit Ctrl-K followed by Ctrl-Right.
If Vim displays <C-Right> it has correctly seen the keystroke and you
should be able to map it (by using <C-Right> as your {lhs}). If it
displays <Right> it has seen the keystroke but as if you hadn't held
Ctrl down: this means your terminal passes Ctrl-Right as if it were just
<Right>. Anything else means the key has been misidentified.

3. If the key is seen, but not as itself and not as some recognizable
key, then there is probably an error in the termcap for the current
terminal. In that case

:set term?

will tell you which termcap entry Vim is using. If you don't see the
same 'term' value on a different type of console (which can happen: e.g.
on my system, KDE konsole and "true" xterm are both detected as xterm),
you can try to add the following to your vimrc:

if &term == <termname>
set <C-Right>=<keycode>
endif

where <termname> above should be replaced by the value of 'term' (with
quotes around it) and <keycode> by what you get when hitting Ctrl-V
followed by Ctrl-Right in Insert mode (with nothing around it).
<C-Right> should be left as-is (9 characters). Don't forget that in a
:set command, white space is not allowed between the = sign and the
value, and any space, double quote, vertical bar or backslash present as
part of the value must be backslash-escaped.

Best regards,
Tony.
