Check Digit Verification of cas no

The CAS Registry Mumber 79971-49-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,9,7 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 79971-49:
(7*7)+(6*9)+(5*9)+(4*7)+(3*1)+(2*4)+(1*9)=196
196 % 10 = 6
So 79971-49-6 is a valid CAS Registry Number.

Reaction of 1,1-dichloroethane with tellurium in the system hydrazine hydrate-potassium hydroxide

Levanova,Grabel'nykh,Kolesnikov,Klyba,Zhanchipova,Albanov,Russavskaya,Korchevin

experimental part, p. 988 - 992 (2011/02/26)

The reaction of 1,1-dichloroethane with tellurium in the system hydrazine hydrate-potassium hydroxide gave ethyltellanyl derivatives as a result of replacement of one chlorine atom in the substrate by tellurium, and of the other, by hydrogen. Probable mechanisms of reduction of the C-Cl bond and mass spectra of the products were considered. The mass spectra of ditelluroacetals revealed unusual rearrangement of the molecular ion, leading to the formation of Te-Te and new C-C bond.
