Check Digit Verification of cas no

The CAS Registry Mumber 1042036-42-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,0,3 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1042036-42:
(9*1)+(8*0)+(7*4)+(6*2)+(5*0)+(4*3)+(3*6)+(2*4)+(1*2)=89
89 % 10 = 9
So 1042036-42-9 is a valid CAS Registry Number.

Convergent and rapid assembly of substituted 2-pyridones through formation of N-alkenyl alkynylamides followed by gold-catalyzed cycloisomerization

Imase, Hidetomo,Noguchi, Keiichi,Hirano, Masao,Tanaka, Ken

supporting information; experimental part, p. 3563 - 3566 (2009/05/07)

(Chemical Equation Presented) A new method for the convergent and rapid assembly of substituted 2-pyridones was developed through the formation of N-alkenyl alkynylamides (amide-linked 1,5-enynes) by N-acylation of !mines with alkynoyl chlorides and the subsequent cationic Au(l)/PPh3-catalyzed cycloisomerization.
