Check Digit Verification of cas no

The CAS Registry Mumber 856820-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,8,2 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 856820-25:
(8*8)+(7*5)+(6*6)+(5*8)+(4*2)+(3*0)+(2*2)+(1*5)=192
192 % 10 = 2
So 856820-25-2 is a valid CAS Registry Number.

Kinetics of Oxidaton of Aliphatic Ketones with Bromamine-T in Acid Medium

Mahadevappa, Dandinasivara S.,Swamy, Putta

, p. 543 - 548 (1988)

The kinetics of oxidation of 2-propanone, 2-butanone, 2-pentanone, 3-pentanone, and 4-methyl-2-pentanone by sodium salt of N-bromo-p-toluenesulfonamide or bromamine-T (BAT) in presence of HClO4 was studied at 30 degC.The rate law is: .Variation of ionic strength of medium or addition of reaction product p-toluenesulfonamide have no effect on the rate.The dielectric effect is positive.The acid-catalyzed enolization of ketone is assumed to be the rate-limiting step and enolization rate coefficients have been calculated.Proton inventory studies made in H2O-D2O mixtures have been employed to calculate the isotropic fractionation factors.Isokinetic temperature is 320 K indicating enthalpy as a controlling factor.
