CAS, a division of the American Chemical Society, is pleased to announce that it will contribute to the Wikipedia project. CAS will work with Wikipedia to help provide accurate CAS Registry Numbers ® for current substances listed in Wikiprojects-Chemicals section of the Wikipedia Chemistry Portal that are of widespread general public interest.
According to CAS, his visionary view of CAS' potential "led to expansion, modernization, and the forging of international alliances with other information organizations." [15] CAS was an early leader in the use of computer technology to organize and disseminate information. [16] The CAS Chemical Registry System was introduced in 1965.
Some registration systems such as the CAS system make use of algorithms to generate unique hash codes to achieve the same objective. A key difference between a registration system and a simple chemical database is the ability to accurately represent that which is known, unknown, and partially known.
CheMoBot adds a template to a _Ref parameter (e.g. for CASNo, CASNo_Ref will be filled with {{cascite|correct|XXX}}) when the bot finds the field correct.The first parameter of the template is 'correct', or 'changed', and the box will show a tick or a cross accordingly on CASNo.

Substructure search is used to retrieve from a database of chemicals those which contain the pattern of atoms and bonds specified by a user. It is implemented using a specialist type of query language and in real-world applications the search may be further constrained using logical operators on additional data held in the database.
Reaxys is a web-based tool for the retrieval of information about chemical compounds and data from published literature, including journals and patents. The information includes chemical compounds, chemical reactions, chemical properties, related bibliographic data, substance data with synthesis planning information, as well as experimental procedures from selected journals and patents.
Following his prediction, Jones asked what will happen if the Giants pick Shedeur first overall and the Raiders are next at No. 2. "See, that's when the game starts to play," Sanders said.
