Check Digit Verification of cas no

The CAS Registry Mumber 1221001-23-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,0,0 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1221001-23:
(9*1)+(8*2)+(7*2)+(6*1)+(5*0)+(4*0)+(3*1)+(2*2)+(1*3)=55
55 % 10 = 5
So 1221001-23-5 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

, p. 988 - 992 (2009)

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.
