eBooks on EBSCOHost houses the eBooks purchased by the Library, covering various academic disciplines such as arts & architecture, business & economics, computer science, education, engineering & technology, health & medicine and mathematics.

You can access the full-text from the computer, or download titles to popular mobile devices.  No overdue fines as the borrowed items will be returned and deleted automatically from MyEBSCOhost folder upon expiry of due date. Reservations can be made by placing titles on hold.

Location of Search Options    

When you log in to CAS SciFindern, search options are presented at the top of the Home page. (You can click the CAS SciFindern logo to return to the Home page at any time.)

All Search finds substances, reactions, references, and suppliers that match your query. 

You can enter search terms that identify the subject of interest (e.g., keyword, research topic, document identifier, patent information, substance name, CAS Registry Number) or draw/import a structure query.

Document Identifier refers to:

• Accession Number
• Document Number
• PubMed ID Number (in quotes)
• Digital Object Indentifier (DOI)

Patent Information refers to:

• Patent Number
• Patent Application Number
• Priority Application Number
• Publication Year
• Accession Number
• Document Number
• PubMed ID Number (in quotes)
• Digital Object Indentifier (DOI)

Structure Query

Click the Draw button in the search field, you have the option to draw the structure using CAS Draw or ChemDoodle.

Structure Query Features

The following structure query features are also available in CAS Draw and ChemDoodle:

Reaction Query Features:

• Specifying Reaction Roles: Specify the reaction roles of the structures by drawing a reaction arrow.
• Marking Reaction Sites: Mark bonds that are changed (broken, formed, or change bond order) in the reaction.
• Mapping Atom Pairs: Specify corresponding pairs of atoms present in the reactant and product.

 Substructure Query Features:

• Variable Atom
• R-group
• Unspecified Bond Type
• Repeating Group
• Variable Attachment Points
• Lock Atom
• Lock Ring

Search field - Substance name, CAS Registry Number, patent identifier, notes, and DOI.

Advanced Search Field(s) - Boolean operator (AND, OR, NOT) + search field values, molecular formula, experimental spectra, and the following property categories: biological/chemical, density, electrical, Lipinski, magnetic, mechanical, optical and scattering, structure related, and thermal. Check the Search key property values only box available for the below properties to focus the property query only on data found in a substance's Key Physical Properties box or preferred substance values:

• Median Lethal Dose (mg/kg)
• Density (g/cm3)
• Electric Conductance (S)
• Electric Conductivity (S/cm)
• Electric Resistance (ohm)
• Electric Resistivity (ohm*cm)
• Magnetic Moment (muB)
• Tensile Strength (Mpa)
• Optical Rotatory Power (degrees)
• Refractive Index
• Boiling Point (°C)
• Glass Transition Temperature (°C)
• Melting Point (°C)

Find Biosequences

There are three biosequence search types:

BLAST (Basic Local Alignment Search Tool): Search for proteins as well as nucleotides using a set of local alignment algorithms (BLASTn, MegaBlast, BLASTp, tBLASTn, BLASTx).

CDR (Complementarity-Determining Region): Search for antibody and t-cell receptors.

Motif: Search for short patterns in DNA, RNA, or proteins with queries enabled for additional variability.

Creating a Retrosynthesis Plan

There are two ways to create a retrosynthesis plan for a substance in CAS SciFindern:

From the Home page with the Retrosynthesis search type

From a substance window
