WuXi AppTec, Leading China-based CRO, Chooses CAS SciFinder(R) to Advance its R&D Competitiveness

SHANGHAI, November 8, 2010 - Chemical Abstracts Service (CAS), the world's authority for chemical
information, announced today that WuXi AppTec, the leading China-based
contract research organization (CRO), has signed a contract to provide
SciFinder for all scientists within their organization. In 2009, a CAS
analysis of chemical literature showed that China led all nations in chemical
patent publications and was surging in output of journal literature. WuXi
AppTec is convincing proof of the continuous investment and ambition of
China-based corporations to lead the world market in the field of chemical
research.

Scientists recognize SciFinder as the first choice for searching and
retrieving chemistry and related scientific information. With streamlined
navigation, an intuitive interface, and secure access to CAS content,
SciFinder makes it simple to quickly find the right information to support
research and make decisions with confidence. "We are pleased to select
SciFinder to advance our R&D competitiveness. As a knowledge-based,
problem-solving provider of broad chemistry-based services, WuXi will have
instant access to more than 10,000 journals and 61 patent authorities, using
an intuitive interface to seek out the latest in state-of-the-art research in
addition to the wealth of a century of scientific information, thereby
enabling our scientific team to more effectively address our customers' needs
in chemistry R&D," commented Dr. Ge Li, chairman and CEO of WuXi AppTec.

China's pharmaceutical market is growing rapidly. In the last decade,
Chinese invention applications increased by nearly 1,400 percent, with much
of that growth taking place in the pharmaceutical sector. More than half of
the Chinese patent applications during this period were from inventors within
China, which indicates that Chinese scientists now also recognize the
importance of monetizing research discoveries. "CAS has served chemists and
other scientists for more than 100 years. We are honored to share our
long-standing experience and comprehensive resources with WuXi AppTec, and
also to be part of the advancement of pharmaceutical discovery and innovation
in China, the fastest growing market in the world," said Robert Massie,
president of CAS.

CAS has already built a solid relationship with hundreds of Chinese
companies and multinational corporations operating in China, along with more
than 80 key universities and research institutions. CAS has partnered for
decades with Chinese organizations, including the State Intellectual Property
Office of the People's Republic of China (SIPO), to build its information
resources.
