Is there a way to detect if a site is on a Content Delivery Network and if yes, can we tell which service are they using?

A:
Just take a look at the urls of the images (and other media) of the site. Reverse lookup IP's of the hostnames you see there and you will see who own them.

You might also be able to tell from the HTTP headers of the media if the URL doesn't give it away. For example, media served by SimpleCDN has Server: SimpleCDN 5.6a4 in its headers.
