Check Digit Verification of cas no

The CAS Registry Mumber 860560-67-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,0,5,6 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 860560-67:
(8*8)+(7*6)+(6*0)+(5*5)+(4*6)+(3*0)+(2*6)+(1*7)=174
174 % 10 = 4
So 860560-67-4 is a valid CAS Registry Number.

A simple and efficient copper oxide-catalyzed Barbier-Grignard reaction of unactivated aryl or alkyl bromides with ester

Gao, Fei,Deng, Xiang-Jun,Tang, Yu,Tang, Jin-Peng,Yang, Jun,Zhang, Yuan-Ming

, p. 880 - 883 (2014)

An efficient one-pot route to synthesize tertiary alcohol compounds using Barbier-Grignard reaction of unactivated alkyl or aryl bromides with ester in THF at 65 C catalyzed by CuO has been developed and systematically investigated. A wide range of substituted tertiary alcohol compounds were obtained in good to high yields. The reaction is highly chemoselective. The mechanism involving the leaving group of R2O-group is discussed.
