Check Digit Verification of cas no

The CAS Registry Mumber 627541-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,7,5,4 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 627541-35:
(8*6)+(7*2)+(6*7)+(5*5)+(4*4)+(3*1)+(2*3)+(1*5)=159
159 % 10 = 9
So 627541-35-9 is a valid CAS Registry Number.

Microwave-Assisted [3 + 2] Cycloadditions of Azomethine Ylides

Bashiardes, George,Safir, Imad,Mohamed, Achmet Said,Barbot, Francis,Laduranty, Joelle

, p. 4915 - 4918 (2007/10/03)

(Equation Presented) The microwave-assisted intramolecular [3 + 2] cycloaddition reaction of azomethine ylides to activated and nonactivated alkenes and alkynes is described. The procedure allows the synthesis of pyrrolidines and pyrrole products in good to excellent overall yields in short reaction times. It appears from parallel comparative studies that the microwave procedure favors the reaction times and overall purity of the crude reaction mixture. The reactions can also be performed in the absence of solvent.
