Check Digit Verification of cas no

The CAS Registry Mumber 901777-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,1,7,7 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 901777-45:
(8*9)+(7*0)+(6*1)+(5*7)+(4*7)+(3*7)+(2*4)+(1*5)=175
175 % 10 = 5
So 901777-45-5 is a valid CAS Registry Number.

Evaluating dynamic kinetic resolution strategies in the asymmetric hydrosilylation of cyclic ketimines

Jones, Simon,Zhao, Peichao

, p. 238 - 244 (2014)

Attempts at performing dynamic kinetic resolution on a series of cyclic ketimines by making use of an asymmetric organocatalysed hydrosilylation gave modest conversion and moderate to good enantioselectivities. In the case of α-tetralone derivatives, the use of an N-benzyl protecting group was found to be crucial in obtaining enhanced levels of selectivity.
