Check Digit Verification of cas no

The CAS Registry Mumber 1238279-17-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,8,2,7 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1238279-17:
(9*1)+(8*2)+(7*3)+(6*8)+(5*2)+(4*7)+(3*9)+(2*1)+(1*7)=168
168 % 10 = 8
So 1238279-17-8 is a valid CAS Registry Number.

Microwave-enhanced rhodium-catalyzed [2+2+2] cycloaddition reactions to afford highly functionalized pyridines and bipyridines

Garcia, Lidia,Pla-Quintana, Anna,Roglans, Anna,Parella, Teodor

experimental part, p. 3407 - 3415 (2010/08/20)

Rhodium(I)-catalyzed [2+2+2] cycloaddition reactions of Ntosyl-, carbon-, and oxygen-tethered cyanodiynes in a completely intramolecular fashion have been optimized to afford highly functionalized pyridines by conventional and/or microwave heating. Microwaves have been shown to enhance the process by allowing the reaction to be conducted effectively in short reaction times. The methodology has been extended for the synthesis of bipyridines, either by treating a cyanodiyne with an appended pyridine or by conducting a double [2+2+2] cycloaddition reaction on a dicyanotetrayne scaffold. The choice of the solvent in the microwave heating reaction has been shown to be crucial for the success of the process.
