Check Digit Verification of cas no

The CAS Registry Mumber 77416-03-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,1 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77416-03:
(7*7)+(6*7)+(5*4)+(4*1)+(3*6)+(2*0)+(1*3)=136
136 % 10 = 6
So 77416-03-6 is a valid CAS Registry Number.

Chlorination of Aliphatic Ketones in Methanol

Gallucci, R. R.,Going, R.

, p. 2532 - 2538 (2007/10/02)

The chlorination of aliphatic ketones in methanol has been examined.The product distributions in methanol differ substantially from those obtained by chlorination in carbon tetrachloride.The reaction in methanol favors addition of chlorine to the least substituted carbon α to the carbonyl group.The effect is especially pronounced if an α carbon bearing two substituents is present.The distribution of products is determined by the relative stability of the enol ethers formed from the ketone under the reaction conditions.
