Check Digit Verification of cas no

The CAS Registry Mumber 1045345-89-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,5,3,4 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1045345-89:
(9*1)+(8*0)+(7*4)+(6*5)+(5*3)+(4*4)+(3*5)+(2*8)+(1*9)=138
138 % 10 = 8
So 1045345-89-8 is a valid CAS Registry Number.

Propargylation of 1,3-dicarbonyl compounds with 1,3-diarylpropynes via oxidative cross-coupling between sp3 C-H and sp3 C-H

Cheng, Dongping,Bao, Weiliang

, p. 6881 - 6883 (2008/12/22)

(Chemical Equation Presented) A highly efficient oxidative-coupling reaction between diarylpropargylic sp3 C-H and active methylenic sp3 C-H was achieved with DDQ as oxidant. The reaction afforded a direct method for the propargylation of 1,3-dicarbonyl compounds, thus providing a concise synthesis of the corresponding products.
