Check Digit Verification of cas no

The CAS Registry Mumber 640772-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,7,7 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 640772-12:
(8*6)+(7*4)+(6*0)+(5*7)+(4*7)+(3*2)+(2*1)+(1*2)=149
149 % 10 = 9
So 640772-12-9 is a valid CAS Registry Number.

2-Pyrazolines from 1,3-Dipolar Cycloaddition of Diazomethane to Arylsulfonylethenes

Padmavathi, Venkatapuram,Sarma, Mudigonda Rajagopala,Padmaja, Adivireddy,Reddy, Dandu Bhaskar

, p. 933 - 937 (2003)

Novel 2-pyrazolines were obtained by the cycloaddition of diazomethane to bis(arylsulfonylethenyl)-sulfones (3) and 1-arylsulfonyl-2-styrylsulfonylethenes (7). Dehydrogenation of 2-pyrazolines with chloranil gave pyrazoles.
