Chemical Abstracts Service numbers

Visithttp //ntp-support.niehs.nih.gov/Main Pages/Chem-HS.html. This is the site for the National Institute of Environmental Health Science. You will find MSDS-type chemical health and safety information from the National Toxicology Program. Chemical searches can be performed by chemical name, synonym, or CAS (Chemical Abstract Service) number.

CAS - Chemical Abstracts Service Number is a US-based service that gives a summary of articles and papers in the scientific and chemical literature that relate to the chemical properties of a compound or substance. Each substance is given a code number and using that code a summary of information can be found. 

The information on each chemical substance is concise and easy to understand. It includes the chemical name with CAS (Chemical Abstracts Service) number, the International Union of Pure and Applied Chemistry (lUPAC) name, molecular formula, synonyms and trade names, use and exposure, toxicity and health effects, whether it is carcinogenic, exposure limits, and methods of proper storage and disposal, with relevant references. Tables and appendices provide additional information. In certain chapters of this book, chemical substances are listed in alphabetical order to facilitate speedy and easy access for the reader the classifications of chemical substances are included separately. 

The Chemical Abstract Service number (CAS) has been added to the substances in order that they might be more easily identified. 

Section 3, Chemical Name and CAS Registry Number, indicates the unique Chemical Abstract Services number for an... 

When responding to hazmat incidents the general public and first responders often have difficulty in accurately determining the exact chemical(s) released. Confusion occurs because chemicals are often identified by product or trade names, placards, labels, or identification numbers, or have different synonyms. Thus, one must first ensure the exact chemical identification (ID). Product or chemical ID can best be determined by referencing the chemical s Chemical Abstract Services number (CAS ). 

These three substances are very similar mixtures obtained from the distillation of coal tars. The physical and chemical properties of each are similar, although limited data are available for coal tar, and coal tar pitch. Chemical Abstracts Service Numbers (CAS ) are associated with coal tar creosote (8001-58-9), coal tar pitch (67996-93-2), and coal tar (8007-45-2). Literature searches for coal tar pitch produce data identical to that obtained for coal tar creosote. A distinction between these materials is provided in the following discussion. 

The glossary has been revised to help users with general chemical terms. Temperatures appear in both Fahrenheit and Celsius using the format (xxx°F/xxx°C). A more detailed description of profile contents appears in the next section. All Chemical Abstract Service Numbers (CAS) have been checked. To save space, many similar and contiguous chemical names and synonyms (with the same CAS number) have been combined into a single entry. Also, foreign language entries, trade names, and common or trivial names of chemicals often used in the workplace or laboratory contain a reference to the main entry (e.g., see methyl ethyl ketone for the MEK entry).

CAS Number (CAS Registration Number). Chemical Abstract Service Number. The Chemical Abstract Service is a registry that assigns unique numbers to chemical substances for identification purposes. 

Information. Identifies the specific chemical product by principal name and other names. Chemical Abstracts Service number (CAS No.), product code (catalog number), and company name with emergency contact information. 

Section 1. The first part of Section 1 identifies the substance by name, formula, and various numbers and codes. Most organic compounds have more than one name. In this case, the systematic (or International Union of Pure and Applied Chemistry [lUPAC]) name is methanol, and the other names are common names or are from an older system of nomenclature. The Chemical Abstract Service Number (CAS No.) is often used to identify a substance, and it may be used to access extensive information about a substance found in many computer databases or in the library. 

Section 1 provides identification numbers and codes for the compound and includes a summary of the risks associated with the use of acetone. Because these sheets are available for many thousands of compounds and mixtures, there must be a means of unambiguously identifying the substance. A standard reference number for chemists is the Chemical Abstracts Service Number (CAS No.).
