Check Digit Verification of cas no

The CAS Registry Mumber 1291093-63-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,1,0,9 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1291093-63:
(9*1)+(8*2)+(7*9)+(6*1)+(5*0)+(4*9)+(3*3)+(2*6)+(1*3)=154
154 % 10 = 4
So 1291093-63-4 is a valid CAS Registry Number.

Sequential Birch reaction and asymmetric Ir-catalyzed hydrogenation as a route to chiral building blocks

Paptchikhine, Alexander,Itto, Kaori,Andersson, Pher G.

, p. 3989 - 3991 (2011)

A range of 1,2,4-trisubstituted cyclohexadienes obtained from the Birch reaction were hydrogenated asymmetrically to produce synthetically valuable chiral compounds in high enantio- and diastereoselectivity. The Royal Society of Chemistry.

Birch reaction followed by asymmetric iridium-catalysed hydrogenation

Cadu, Alban,Paptchikhine, Alexander,Andersson, Pher G.

experimental part, p. 3796 - 3800 (2012/01/06)

Birch reaction products are asymmetrically hydrogenated with high enantio- and diastereoselectivity via iridium catalysts. This new method of producing chiral compounds was explored for a variety of 1,3-di- and 1,2,4-tri-substituted cyclohexadienes. Georg
