Check Digit Verification of cas no

The CAS Registry Mumber 22027-16-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,0,2 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 22027-16:
(7*2)+(6*2)+(5*0)+(4*2)+(3*7)+(2*1)+(1*6)=63
63 % 10 = 3
So 22027-16-3 is a valid CAS Registry Number.

Kinetic Studies of the Formation of Dithizone. Part-I. Alkali assisted Conversion of Phenylhydrazinium Phenylhydrazine Dithiocarbamate and Diphenylthiocarbazide

Sarangi, B.,Misra, B. K.,Behera, G. B.

, p. 979 - 982 (2007/10/02)

The kinetics of formation of dithizone (3) from phenylhydrazinium phenylhydrazine dithiocarbamate (1) and from phenylthiocarbazide (2) has been studied.The synthetic aspect of the formation of dithizone from phenylhydrazine and carbon disulphide has also been worked out.A mechanism for the formation of dithizone from 1 and 2 has been proposed.
