Check Digit Verification of cas no

The CAS Registry Mumber 53219-49-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,2,1 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 53219-49:
(7*5)+(6*3)+(5*2)+(4*1)+(3*9)+(2*4)+(1*9)=111
111 % 10 = 1
So 53219-49-1 is a valid CAS Registry Number.

Abstract: N,N,N′,N′-Tetrachlorobenzene-1,3-disulfonamide and poly(N,N′-dichloro-N-ethyl-benzene-1,3-disulfonamide) are new catalysts promoted by one-pot, facile and four-component synthesis of new substituted 1,4-dihydropyridine derivatives from the react

Microwave assisted combinatorial chemistry. Synthesis of substituted pyridines

Cotterill, Ian C.,Usyatinsky, Alexander Ya.,Arnold, John M.,Clark, Douglas S.,Dordick, Jonathan S.,Michels, Peter C.,Khmelnitsky, Yuri L.

, p. 1117 - 1120 (2007/10/03)

A new highly efficient MICROCOS technology (Microwave-assisted Combinatorial Synthesis) for generating combinatorial libraries is described. The technology is applied to the high throughput, automated, one-step, parallel synthesis of diverse substituted pyridines using the Hantzsch synthesis. The advantages of microwave-assisted chemistry for combinatorial synthesis include a broad range of available chemistries, simple reaction setup and product recovery readily amenable to automation, extremely short reaction times, and high product yields.
