Check Digit Verification of cas no

The CAS Registry Mumber 54756-41-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,7,5 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 54756-41:
(7*5)+(6*4)+(5*7)+(4*5)+(3*6)+(2*4)+(1*1)=141
141 % 10 = 1
So 54756-41-1 is a valid CAS Registry Number.

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 (1998)

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.
