CAS Science Spotlight Most Requested Chemistry and Related Science

CAS, the world's leader in providing chemical information, is now highlighting the most requested documents using Real-Time Document Request (RDR) ranking. Tallying researchers' actual requests (RDRs) for full-text articles via CAS online services establishes a new method of evaluating the actual use of scientific journals by scientists engaged in daily research.

Aggregated data has been used to develop this ranking; activity of individual users is not tracked.

CAS provides this information as a free service to the scientific community.
