Check Digit Verification of cas no

The CAS Registry Mumber 60449-44-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,4,4 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 60449-44:
(7*6)+(6*0)+(5*4)+(4*4)+(3*9)+(2*4)+(1*4)=117
117 % 10 = 7
So 60449-44-7 is a valid CAS Registry Number.

COPPER(II) EXTRACTION BY ALKYL- AND ALKENYL-SUBSTITUTED 8-QUINOLINOLS

Cerny, Mirko,Vilimec, Jan,Stastova, Jitka,Rod, Vladimir,Kraus, Milos

, p. 922 - 933 (2007/10/02)

The equilibrium and kinetics of copper extraction from water solutions of copper(II) perchlorate into chloroform by 8-quinolinol, 2-methyl-8-quinolinol, six 7-alkenyl-8-quinolinols (with C3 to C12 side chains) and by 7-(p-tert.butylbenzyl)-8-quinolinol were measured.The data were treated by previuously derived models which take into account the complex nature of the extraction process.The equilibrium data were expressed as extraction constants Kex, the rate data as the rate parameter Θ and initial extraction rates Jo, respectively.The influence of the position,size and structure of the substituents on these parameters is discussed.A strong effect of the position of the double bond C=C in the side chain was found.
