Check Digit Verification of cas no

The CAS Registry Mumber 1264833-16-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,4,8,3 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1264833-16:
(9*1)+(8*2)+(7*6)+(6*4)+(5*8)+(4*3)+(3*3)+(2*1)+(1*6)=160
160 % 10 = 0
So 1264833-16-0 is a valid CAS Registry Number.

Asymmetric synthesis of all-carbon quaternary stereocenters via desymmetrization of 2,2-disubstituted 1,3-propanediols

Lee, Ji Young,You, Young Suk,Kang, Sung Ho

, p. 1772 - 1774 (2011/04/23)

A novel enantioselective desymmetrization of 2,2-disubstituted 1,3-propanediols has been established to generate all-carbon quaternary stereocenters, which has been implemented with BzCl and Et3N in the presence of Pybox(6)-CuCl2 complex in CH2Cl2 or PhMe at 78°C. While all the cyanide-comprising diols were desymmetrized with superb enantioselectivity (higher than 98% ee), the stereoinduction of the other substrates greatly depends on the size difference between the two substituents at the 2-position. When the size difference becomes larger, the corresponding substrates tend to engender enhanced enantioselectivity (up to 99% ee).
