Check Digit Verification of cas no

The CAS Registry Mumber 117667-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,6 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 117667-83:
(8*1)+(7*1)+(6*7)+(5*6)+(4*6)+(3*7)+(2*8)+(1*3)=151
151 % 10 = 1
So 117667-83-1 is a valid CAS Registry Number.

Catalyst development for organocatalytic hydrosilylation of aromatic ketones and ketimines

Malkov, Andrei V.,Stewart-Liddon, Angus J. P.,McGeoch, Grant D.,Ramirez-Lopez, Pedro,Kocovsky, Pavel

experimental part, p. 4864 - 4877 (2012/07/28)

A new family of Lewis basic 2-pyridyl oxazolines have been developed, which can act as efficient organocatalysts for the enantioselective reduction of prochiral aromatic ketones and ketimines with trichlorosilane, a readily available and inexpensive reagent. 1-Isoquinolyl oxazoline, derived from mandelic acid, was identified as the most efficient catalyst of the series, capable of delivering high enantioselectivities in the reduction of both ketones (up to 94% ee) and ketimines (up to 89% ee).
