Knowledge Graph - Version 2.0

Gaining an understanding of the competitive landscape before starting a research project has been made easier with new enhancements to Knowledge Graph. A variety of updates have been made including updating the content key, maintaining sticky preferences for turning nodes off, a search feature, updating the colors of the nodes and edges, and enhancing highlighting behaviors within the graph.


GHS Data

Code, statements, and pictograms from the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), are now available in CAS SciFinderⁿ. This data provides critical insights to use restrictions and warnings associated with substances.

Support Multi-Term Substance Name Searching in References

Precision Search in CAS SciFinderⁿ has been enhanced to recognize multi-term substance names in addition to multi-term thesaurus entries. When a multi-term substance entry is recognized, the individual terms comprising the entry are not searched as individual terms.

When a multi-term substance is recognized in a reference query, that substance is searched not only as an indexed entry for a document, but also in titles, abstracts, and keywords (similar to using a bound phrase (quotation marks) in a query).
