Check Digit Verification of cas no

The CAS Registry Mumber 20364-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,6 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20364-70:
(7*2)+(6*0)+(5*3)+(4*6)+(3*4)+(2*7)+(1*0)=79
79 % 10 = 9
So 20364-70-9 is a valid CAS Registry Number.

Cis-selective and highly enantioselective hydrogenation of 2,3,4-trisubstituted quinolines

Zhang, Zhenhua,Du, Haifeng

, p. 2816 - 2819 (2015)

A highly enantioselective cis-hydrogenation of 2,3,4-trisubstituted quinolines has been realized for the first time using chiral borane catalysts generated in situ from chiral dienes. A variety of tetrahydroquinoline derivatives containing three contiguous stereogenic centers were obtained in 76-99% yields with 82-99% ee's.
