Check Digit Verification of cas no

The CAS Registry Mumber 20503-96-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,0 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20503-96:
(7*2)+(6*0)+(5*5)+(4*0)+(3*3)+(2*9)+(1*6)=72
72 % 10 = 2
So 20503-96-2 is a valid CAS Registry Number.

Microwave induced 1,3-Dipolar cycloaddition reactions of nitrones

Baruah, Bipul,Prajapati, Dipak,Boruah, Anima,Sandhu, Jagir S.

, p. 2563 - 2567 (2007/10/03)

1,3-Dipolar cycloaddition reactions involving unreactive nitrones have been carried out successfully under microwave irradiations. The reaction of nitrones I and alkene 2 proceeded regiospecifically at atmospheric pressure and the corresponding isoxazolidines 3 were obtained in high yields.
