Check Digit Verification of cas no

The CAS Registry Mumber 1643718-45-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,3,7,1 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1643718-45:
(9*1)+(8*6)+(7*4)+(6*3)+(5*7)+(4*1)+(3*8)+(2*4)+(1*5)=179
179 % 10 = 9
So 1643718-45-9 is a valid CAS Registry Number.

Desymmetrization of diolefinic diols by enantioselective amino-thiocarbamate-catalyzed bromoetherification: Synthesis of chiral spirocycles

Tay, Daniel Weiliang,Leung, Gulice Y. C.,Yeung, Ying-Yeung

, p. 5161 - 5164 (2014/05/20)

A facile, efficient, and highly diastereo- and enantioselective bromoetherification of diolefinic diols has been developed using an amino-thiocarbamate catalyst. Further manipulations of the bromoether products enabled entry into a new class of spirocycle
