The power of the human connection

The scientists who build the CAS Content Collection™ are united by a shared purpose: accelerating discoveries that improve lives.
Every day, they curate, connect, and analyze global literature, knowing their work impacts countless research projects worldwide.

Expert curation delivers reliable data

Hundreds of scientists with expertise spanning chemistry, biology, materials science, and many other scientfic disciplines curate the CAS Content Collection.

Our curation model combines:

Specialized knowledge: Understanding context, catching errors, making critical connections

Advanced technology: AI and machine learning to process volume and identify patterns

Rigorous quality: Multi-layer validation to ensure every data point is accurate

While technology helps us process 100,000+ documents daily, human intelligence ensures the connections are meaningful and the insights are trustworthy.

Uniting global knowledge

Scientific discoveries are published worldwide in diverse formats, languages, and styles. Critical insights are buried in dense documents, trapped in images and diagrams, expressed in specialized notation, or disclosed in languages most researchers can't read.

Talented CAS scientists and researchers transform what others cannot. What the scientific world publishes in fragments, they deliver as structured, connected, decision-ready knowledge.

The CAS curation process

Transforming disconnected data points into structured, decision ready knowledge to fuel your next discovery.

2

Extract

Identify, capture, and connect key details: substances from images, reactions from schemes, sequences from tables, and insights from text.

02

3

Standardize

Convert diverse formats into consistent, machine-readable structures using controlled vocabularies and authority constructs.

03

4

Connect

Link related concepts across documents: substances to reactions, diseases to targets, patents to prior art, creating a powerful knowledge graph spanning over a century.

04

5

Validate

Multi-layer quality checks ensure accuracy, consistency, and completeness.
