Advancing the accuracy of open chemical information with CAS common chemistry

Open resources from authoritative sources are a key driver of open data quality. The recent relaunch of CAS Common Chemistry, which expands the resource to include nearly 500,000 substances from CAS REGISTRY® and offers this content for community use under a Creative Commons Attribution-NonCommercial (CC BY-NC 4.0) license, offers a unique opportunity to boost the accuracy of open chemical information. In this talk, the authors will highlight work done to date to leverage the expanded resource in enhancing data quality across open resources, including Wikipedia and Wikidata.
