1044500-74-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1044500-74-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,4,5,0 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1044500-74:
(9*1)+(8*0)+(7*4)+(6*4)+(5*5)+(4*0)+(3*0)+(2*7)+(1*4)=104
104 % 10 = 4
So 1044500-74-4 is a valid CAS Registry Number.

Base- and ligand-free room-temperature synthesis of N-fused heteroaromatic compounds via the transition metal-catalyzed cycloisomerization protocol

Seregin, Iiya V.,Schammel, Alex W.,Gevorgyan, Vladimir

, p. 3433 - 3436 (2007)

A new practical method for the synthesis of N-fused heterocycles via the transition metal-catalyzed cycloisomerization of heterocyles possessing a propagyl group has been developed. This very mild, base- and ligand-free method allows for the synthesis of diverse fused heterocyclic cores in good to excellent yields.
