The Royal Society of Chemistry have recently produced a series of video tutorials on the
ACD / I-Lab service.
ACD / I-Lab provides predictions based on chemical structures, including physicochemical properties, NMR spectra and chemical shifts, and ADME toxicities. Structures can be input in a variety of forms - draw a structure using the I-Lab interface, or look up a compound using the built in dictionary.
You can view the tutorials via the RSC YouTube channel.
University of Sheffield members can access the Chemical Database Service via the Library webpages.
