Check Digit Verification of cas no

The CAS Registry Mumber 1379689-25-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,9,6,8 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1379689-25:
(9*1)+(8*3)+(7*7)+(6*9)+(5*6)+(4*8)+(3*9)+(2*2)+(1*5)=234
234 % 10 = 4
So 1379689-25-4 is a valid CAS Registry Number.

Cooperative Lewis acid-onium salt catalysis as tool for the desymmetrization of meso-epoxides

Broghammer, Florian,Brodbeck, Daniel,Junge, Thorsten,Peters, René

supporting information, p. 1156 - 1159 (2017/01/25)

Epoxide desymmetrizations by bromide are very rare despite the large synthetic potential of chiral bromohydrins. Herein we present a new concept for epoxide desymmetrizations in which a bifunctional Lewis acid/ammonium salt catalyst allows for efficient enantio-selective epoxide ring openings by Br. With acetylbromide as a Br source bromohydrin esters are formed.
