Check Digit Verification of cas no

The CAS Registry Mumber 167422-39-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,4,2 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 167422-39:
(8*1)+(7*6)+(6*7)+(5*4)+(4*2)+(3*2)+(2*3)+(1*9)=141
141 % 10 = 1
So 167422-39-1 is a valid CAS Registry Number.

Enantioselective Conjugate Addition of Primary Dialkylzinc Reagents to 2-Aryl- and 2-Heteroaryl-nitroolefins Mediated by Titanium-TADDOLates Preparation of Enantioenriched 2-Aryl-alkylamines

Schaefer, Harald,Seebach, Dieter

, p. 2305 - 2324 (2007/10/02)

The addition of dialkylzinc to nitroolefins is catalyzed by Lewis acids such as MgBr2, MgI2, and chlorotitanates.Using the (R,R)-Ti-TADDOLates the addition of diethyl-, dibutyl-, and dioctyl zinc to 2-aryl-nitroethenes is shown to be enantioselective with
