Check Digit Verification of cas no

The CAS Registry Mumber 143084-52-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,0,8 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143084-52:
(8*1)+(7*4)+(6*3)+(5*0)+(4*8)+(3*4)+(2*5)+(1*2)=110
110 % 10 = 0
So 143084-52-0 is a valid CAS Registry Number.

Reactions of Isoprene with Secondary Amines

Kazantsev, O. A.,Shirshin, K. V.,Danov, S. M.,Afon'shin, G. N.

, p. 300 - 303 (2007/10/03)

Reactions of isoprene with secondary amines in the presence of alkali metals yield isomeric aminoolefins: 1-dialkylamino-3-methyl-2-butenes, 1-dialkylamino-2-methyl-2-butenes, and 1-dialkylamino-3-methyl-1-butenes.The influence of temperature, structure of the secondary amine, amount of catalyst, and molar ratio of the reactants on the yield of aminoolefins and selectivity of their formation has been examined.
