Check Digit Verification of cas no

The CAS Registry Mumber 28285-60-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,8 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28285-60:
(7*2)+(6*8)+(5*2)+(4*8)+(3*5)+(2*6)+(1*0)=131
131 % 10 = 1
So 28285-60-1 is a valid CAS Registry Number.

Conformational and steric effects on the oxidation of some substituted tetrahydrothiopyran-4-ones and their 1,1-dioxides by pyridinium fluorochromate

Pillay, M. Krishna,Kasthuri

, p. 738 - 744 (2007/10/03)

Kinetics of oxidation of the title compounds by pyridinium fluorochromate (PFC) in the presence of perchloric acid in aqueous acetic acid medium has been studied. The reactions show first order dependence each on [oxidant] and [substrate] and are observed to be acid-catalysed. An increase in polarity of the medium is found to decrease the rate and the variation in ionic strength of the medium has no significant influence on the rate of oxidation. All the reactions have been carried out at four different temperatures and various activation parameters are evaluated. The oxidation products have been isolated and characterised. Plausible mechanisms consistent with the observed kinetic results have been formulated. The relative reactivities of these compounds have also been rationalised based on their conformational differences and steric factors.
