Check Digit Verification of cas no

The CAS Registry Mumber 337308-27-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,7,3,0 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 337308-27:
(8*3)+(7*3)+(6*7)+(5*3)+(4*0)+(3*8)+(2*2)+(1*7)=137
137 % 10 = 7
So 337308-27-7 is a valid CAS Registry Number.

Reactivity of bifunctional olefins with hydrazine hydrate - Part II

Bhaskar Reddy,Rajagopal Sarma,Somasekhar Reddy,Subba Reddy

, p. 901 - 903 (2007/10/03)

The reaction of 1-aroyl-2-arylsulfonylethenes 1 with different ratios of hydrazine hydrate lead to hydrazones, dimerized products and 2-pyrazolines. The reactivity of pyrazolines has also been studied by dehydrogenation, pyrolysis, nitrosation and acylation.
