A Chemical Abstracts Service Registry Number, also assigned to as CASRN or CAS No, is an exclusive algebraic accessory authorized by Chemical Abstracts Service (CAS) to every chemical product explained in the open scientific literature (presently along with those characterized from at least 1957 through the present), involving organic and inorganic compounds, metals, isotopes, amalgam and non-structural elements such as UVCBs, of unknown, variable composition, or biological origin etc.

The register managed by Chemical Abstracts Service is an authentic selection of published chemical element instructions. Recently the Chemical Abstracts Service Registry classifies more than 81 million organic and inorganic elements and 64 million protein and DNA series, plus extra data about each and every element. The register is refurbished with an accurate 15,000 more new elements every day.

When you require to absolutely determining a chemical element, you may expect on the authentic cause for chemical names and design of CAS Registry. You may also analyze your material of importance by its CAS No, which is globally used to ...
... offer a special, error free classifier for chemical elements.

You can also use CAS Registry to establish

• Biography remarks to the object
• Exploratory and concluded perfect data (for example: boiling and melting points, etc.)
• CA Index Names and metonym
• Commercial opening
• Preparatory processes
• Spectra
• Managerial instruction from international assets

You may access the instruction you require for millions of materials from the most recent and durable selection of chemical elements instruction in the world, CAS Register.

Content

• Substances reported in the literature back to the early 1800s
• Updated daily with about 15,000 substances
• Substance information enriched with experimental and predicted property data, including more than 5.1 billion property values, data tags and spectra

How do we count?

Each chemical hold its individual and specific Chemical Abstracts Service Registry Number. A number which belongs to an unique chemical cannot be duplicated or used to represent some other chemical.
It has no basic meaning but it is allowed in consecutive, enhancing order when the element is classified by Chemical Abstract Service (CAS) Scientist for the admittance in the CAS registry document.

Chemical Abstract Service Registry Number is distinguished by hyphens into 3 sections, the first part includes up to 7 digits, second section includes of 2 digits, and the third part includes at least a single digit which acts as a check digit.

The CAS Register bibliography includes documents for particular elements determined by the Chemical Abstracts Service (CAS) registry method.

All element registers include a specific Chemical Abstracts Service Registry Number. Documents may also have CA index names, metonyms, structural diagrams, stereochemistry, molecular blueprint, ring data, alloy arrangement tables, protein and nucleic acid series, classes for polymers, and the number of references in the CA or CA plus databases. All of this instruction is displayable and searchable on STN, but some of it is only displayable in SciFinder.

In addition to product information, registry documents include super parts and record type information from CA plus, searchable and predicted (calculated) property data, and labels indicating to remarks along with exploratory property data.
