What is CAS compound in chemistry?
Definition. A CAS (Chemical Abstracts Service) Registry Number is a unique identifier that tells you, for example, that acetone and dimethyl ketone are actually the same substance.
How many chemicals are in CAS?
Nearly 500,000 chemical substances from CAS REGISTRY® cover areas of community interest, including common and frequently regulated chemicals, and those relevant to high school and undergraduate chemistry classes.
What is SciFinder used for?
SciFinder, produced by Chemical Abstracts Service (CAS), is the most comprehensive database for the chemical literature, searchable by topic, author, substances by name or CAS Registry Number, OR use the editor to draw chemical structures, substructures, or reactions.
How do you get a CAS Number?
A CAS Registry Number is assigned to a substance when it enters the CAS REGISTRY database. Numbers are assigned in sequential order to unique, new substances identified by CAS scientists for inclusion in the database.
What is a full form of CAS?
The Central Authentication Service (CAS) is a single sign-on protocol for the web. Its purpose is to permit a user to access multiple applications while providing their credentials (such as userid and password) only once. The CAS system uses the IAS LDAP to authenticate users.

How long is CAS valid for?
six months
A CAS is only valid for six months from the date it is issued. When you make your student visa application you must include all original documents stated on your CAS, where required (low-risk nationals do not need to submit original documents). Failure to do so could result in a visa refusal.
Who can use SciFinder?
Remember SciFinder must only be used for academic research – commercial research is not permitted. You can search SciFinder by chemical substance, reaction, research topic, author and company name.
How much does SciFinder cost?
How much does SciFinder cost? An academic institution or user can subscribe to the task-based, commercial version of SciFinder for $6,500 per year for 310 tasks. Each search is considered a task, and a substructure search counts as four tasks.
How long does it take to get a CAS letter?
The institution will verify the set of documents provided by the students and once confirmed, you will receive the letter in 2-3 business days (can take a few days more). Although CAS is an important document, yet there is no fixed duration of time that is taken by a university to release it.
Why is having a CAS number important?
They are assigned to a compound as the CAS registers a new compound. The number has no significance to the chemistry, structure, or chemical nature of the molecule. The CAS Number of a compound is a useful way to identify a chemical over its name.
