Check Digit Verification of cas no

The CAS Registry Mumber 21336-43-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,3 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21336-43:
(7*2)+(6*1)+(5*3)+(4*3)+(3*6)+(2*4)+(1*3)=76
76 % 10 = 6
So 21336-43-6 is a valid CAS Registry Number.

Chlorination of Adamantane and Its Derivatives by Carbon Tetrachloride in the Presence of Manganese-, Vanadium-, and Molybdenum-containing Catalysts

Khusnutdinov,Shchadneva,Baiguzina,Lavrent'eva,Burangulova,Dzhemilev

, p. 126 - 133 (2007/10/03)

The feasibility of catalytic chlorination of adamantane and its derivatives by carbon tetrachloride in the presence of manganese-, vanadium-, and molybdenum-containing catalysts activated by nitrile ligands or alcohols was established. The optimum molar ratios of catalyst components and reactants and the optimum reaction conditions for selective syntheses of mono-, di-, and trichlorosubstituted adamantane derivatives with high yields were found.
