How many chemical substances are there? 100,000,000 (in CAS Registry)

US Chemical Abstracts Service registers 100 millionth chemical substance in CAS REGISTRY – 30 Jun 2015

Chemical Abstracts Service (CAS), the world’s authority for chemical information, has registered the 100 millionth chemical substance in the CAS REGISTRY, in the 50th anniversary year of the world’s largest database of unique chemical substances.

With a steady increase in patenting activity around the globe, it is not surprising the 100 millionth small molecule registration comes from a patent. In this case, the substance was reported in a World Intellectual Property Organization (WIPO) patent from Coferon, Inc. (Coferon) in Stony Brook, NY. The inventors claim the molecule, CAS RN 1786400-23-4, available in both SciFinder® and STN®, is a novel therapeutic designed to treat acute myeloid leukemia.

Started in 1965 as a project to uniquely identify and track chemical substance information, the CAS Registry system is the only complete and accurate source of unique identifiers, known as CAS Registry Numbers for all organic and inorganic substances disclosed in scientific publications and other reputable sources. Today, scientists, intellectual property professionals and compliance specialists around the world rely on CAS Registry Numbers to instantaneously identify and access the exact chemical needed for their research, safety and compliance needs.

The invention of CAS REGISTRY revolutionized the chemical information field and transformed research since the mid 60’s, and CAS Registry Numbers are ubiquitous in mainstream society today. Global regulatory organisations, including the United States Environmental Protection Agency and The ACT on the Registration and Evaluation of Chemicals regulatory body in Korea, require all new chemical substances manufactured or imported to be identified by a CAS Registry Number. These are also used on Materials Safety Data Sheets (MSDS) around the world as a reliable resource for safe handling and transport of chemicals. CAS Registry Numbers are found on consumer products we use, e.g., paint cans and shampoo labels, and are relied upon in numerous web information sources, including chemical suppliers sites, Wikipedia, PubChem, and ChemSpider, to provide the one unique key that can open the world of information about that substance.

The substantial growth in worldwide chemical discoveries over the past 10 years is reflected in CAS REGISTRY. A view of all substances added since 1965 shows that the pace of research has significantly accelerated in the past ten years. Of the 100 million substances in CAS REGISTRY, approximately 75 million were added over the past 10 years. On average, CAS has registered 1 substance every 2.5 minutes over the past 50 years.

The Plant List

  • http://www.theplantlist.org/

    “As the website rather modestly states, The Plant List is “a working list of all known plant species.” In other words, botanically inspired readers will find on this site basic information about 1,293,685 (and counting) different plants. Readers may like to begin with How to use this site, a comprehensive section that describes how to search The Plant List, when it is useful or not useful to conduct a search, when it is more helpful to browse, and other tips and tidbits. After getting their bearings, readers may then want to delve into the list itself. For instance, the Browse tab allows readers to look into the four major groups (flowering plants, conifers, ferns, and mosses), and then dig down into family, genera, and species. For science teachers looking for new resources to offer their students, or for anyone fascinated by plants, this collaboration between the Royal Botanical Gardens, Kew, and the Missouri Botanical Garden is a truly comprehensive resource.

“University of Toronto, May 5, 2015.  Summary: A recent and famous image from deep space marks the first time we’ve seen a forming planetary system, according to a study by astrophysicists. The team found that circular gaps in a disk of dust and gas swirling around the young star HL Tau are in fact made by forming planets.”

Viruses: Timeline, Structure, Biology

From Genetic Engineering &  Biotechnology News (GEN), March 15, 2015

URL:virologyhistory.wustl.edu/index.htm

“Sure, the year 1941 may best be remembered for being the year of the attack on Pearl Harbor, but it was also the year in which X-ray diffraction patterns were obtained for the tomato bushy stunt virus (TBSV) and tobacco mosaic virus (TMV). You can find this and other world history/structural biology history side-by-side comparisons in the nifty timeline feature on the Viruses: From Structure to Biology website. This site—the creation of Sondra and Milton Schlesinger at Washington University School of Medicine —provides some nice background on key milestones in structural virology and the resulting biological breakthroughs in the field. There isn’t a ton of information on the site—one might call it a single-serving website—but within that serving you’ll be able to chew on some interesting science history.”
