Check Digit Verification of cas no

The CAS Registry Mumber 70668-35-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,6,6 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70668-35:
(7*7)+(6*0)+(5*6)+(4*6)+(3*8)+(2*3)+(1*5)=138
138 % 10 = 8
So 70668-35-8 is a valid CAS Registry Number.

Design of a New Bimetallic Catalyst for Asymmetric Epoxidation and Sulfoxidation

Bhadra, Sukalyan,Akakura, Matsujiro,Yamamoto, Hisashi

supporting information, p. 15612 - 15615 (2016/01/09)

A new chiral tethered 8-quinolinol-based ligand class is developed. The binuclear titanium complex of the ligand operates through a novel mechanism allowing for the regio- and stereoselective epoxidation of primary and tertiary homoallylic alcohols (up to 98% ee), as well as first examples of 2-allylic phenols (up to 92% ee). The new catalyst system also promotes the asymmetric oxidation of γ-hydroxypropyl sulfides giving an important class of chiral sulfoxides that have been inaccessible to date (up to 95% ee).
