  2. CAS Registry Number - Wikipedia

    en.wikipedia.org/wiki/CAS_Registry_Number

    The CAS Registry is an authoritative collection of disclosed chemical substance information. It identifies more than 204 million unique organic and inorganic substances and 69 million protein and DNA sequences, [3] plus additional information about each substance. It is updated with around 15,000 additional new substances daily. [5]

  3. List of CAS numbers by chemical compound - Wikipedia

    en.wikipedia.org/wiki/List_of_CAS_numbers_by...

    This is a list of CAS numbers by chemical formulas and chemical compounds, indexed by formula.The CAS number is a unique number applied to a specific chemical by the Chemical Abstracts Service (CAS).This list complements alternative listings to be found at list of inorganic compounds and glossary of chemical formulae

  4. Chemical Abstracts Service - Wikipedia

    en.wikipedia.org/wiki/Chemical_Abstracts_Service

    The CAS Chemical Registry System was introduced in 1965. CAS developed a unique registry number to identify chemical substances. Agencies such as the U.S. Environmental Protection Agency and local fire departments around the world now rely on these numbers for the definite identification of substances. According to the ACS, this is the largest ...

  5. Chemical nomenclature - Wikipedia

    en.wikipedia.org/wiki/Chemical_nomenclature

    Chemical nomenclature. Chemical nomenclature is a set of rules to generate systematic names for chemical compounds. The nomenclature used most frequently worldwide is the one created and developed by the International Union of Pure and Applied Chemistry (IUPAC). IUPAC Nomenclature ensures that each compound (and its various isomers) have only ...

  6. Safety data sheet - Wikipedia

    en.wikipedia.org/wiki/Safety_data_sheet

    The American Chemical Society defines Chemical Abstracts Service Registry Numbers (CAS numbers) which provide a unique number for each chemical and are also used internationally in SDSs. Reviews of material safety data sheets by the U.S. Chemical Safety and Hazard Investigation Board have detected dangerous deficiencies.

  7. Chemical compound - Wikipedia

    en.wikipedia.org/wiki/Chemical_compound

    A chemical formula specifies the number of atoms of each element in a compound molecule, using the standard chemical symbols with numerical subscripts. Many chemical compounds have a unique CAS number identifier assigned by the Chemical Abstracts Service. Globally, more than 350,000 chemical compounds (including mixtures of chemicals) have been ...

  8. Group (periodic table) - Wikipedia

    en.wikipedia.org/wiki/Group_(periodic_table)

    Two earlier group number systems exist: CAS (Chemical Abstracts Service) and old IUPAC. Both use numerals (Arabic or Roman) and letters A and B. Both systems agree on the numbers. The numbers indicate approximately the highest oxidation number of the elements in that group, and so indicate similar chemistry with other elements with the same ...

  9. Glossary of chemical formulae - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_chemical_formulae

    This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds. There is no complete list of chemical compounds since by nature the list would be infinite.
