Check Digit Verification of cas no

The CAS Registry Mumber 71612-09-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,1 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71612-09:
(7*7)+(6*1)+(5*6)+(4*1)+(3*2)+(2*0)+(1*9)=104
104 % 10 = 4
So 71612-09-4 is a valid CAS Registry Number.

Selective Cleavage of Dimethylhydrazones to the Carbonyl Compounds Using Silica Gel and its Application in the Synthesis of (Z)-9-Tetradecenyl Acetate

Mitra, R. B.,Reddy, G. Bhaskar

, p. 694 - 698 (2007/10/02)

A new method for the selective hydrolytic cleavage of dimethylhydrazones consists of treatment of the hydrazones with silica gel (pH 6.80) in wet tetrahydrofuran.Utilizing this method as one of the key steps, (Z)-9-tetradecenyl acetate, the pheromone of Spodoptera frugiperda, was synthesized.
