Check Digit Verification of cas no

The CAS Registry Mumber 1224096-89-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,4,0,9 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1224096-89:
(9*1)+(8*2)+(7*2)+(6*4)+(5*0)+(4*9)+(3*6)+(2*8)+(1*9)=142
142 % 10 = 2
So 1224096-89-2 is a valid CAS Registry Number.

N-Substituted and N-unsubstituted 1,3-Oxazolium-5-olates cycloaddition reactions with 3-substituted coumarins

Cordaro, Massimiliano,Grassi, Giovanni,Risitano, Francesco,Scala, Angela

experimental part, p. 2713 - 2717 (2010/05/02)

The 1,3-dipolar cycloaddition reaction of unsymmetrically N-substituted and N-unsubstituted 1,3-oxazolium-5-olates with selected 3-substituted coumarins has been examined. Various types of pyrrole derivatives are isolated and their formation seems to be a function of the regio- and diastereochemistry of the initial cycloaddition step.
