Check Digit Verification of cas no

The CAS Registry Mumber 129410-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,1 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 129410-12:
(8*1)+(7*2)+(6*9)+(5*4)+(4*1)+(3*0)+(2*1)+(1*2)=104
104 % 10 = 4
So 129410-12-4 is a valid CAS Registry Number.

Diels-Alder Reactivity of Pyranoindol-3-ones, Indole 2,3-Quinodimethane Analogues

Moody, Christopher J.,Rahimtoola, Kulsum F.

, p. 673 - 679 (2007/10/02)

The pyranoindol-3-ones (7) are stable indole-2,3-quinodimethane type dienes, which undergo Diels-Alder reaction with alkynes to give, after loss of carbon dioxide, carbazoles.The reactivity of the diene is increased by the presence of the electron-withdrawing t-butoxycarbonyl group on the indole nitrogen.The pyranoindolones (7) are less reactive, and exhibit the opposite regiochemistry in their Diels-Alder reactions than the isomeric pyranoindol-3-ones (1).Factors which affect the regiochemistry of the Diels-Alder reaction are discussed.
