Check Digit Verification of cas no

The CAS Registry Mumber 85254-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,2,5 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 85254-20:
(7*8)+(6*5)+(5*2)+(4*5)+(3*4)+(2*2)+(1*0)=132
132 % 10 = 2
So 85254-20-2 is a valid CAS Registry Number.

Palladium-catalyzed coupling/cyclization reactions of allene-substituted lactams

Karstens, Willem F. J.,Rutjes, Floris P. J. T.,Hiemstra, Henk

, p. 6275 - 6278 (2007/10/03)

ω-(2,3-Butadienyl)lactams react with aryl iodides in the presence of n-Bu4NCl, K2CO3 and a catalytic amount of Pd(PPh3)4 to give bicyclic enamides resulting from attack of nitrogen on the central carbon and transfer of the aryl group to the terminal carbon and of the allene.
