Check Digit Verification of cas no

The CAS Registry Mumber 21553-46-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,5 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21553-46:
(7*2)+(6*1)+(5*5)+(4*5)+(3*3)+(2*4)+(1*6)=88
88 % 10 = 8
So 21553-46-8 is a valid CAS Registry Number.

Steric Enhancement of Resonance-Evidence from Kinetic Study on some Acetophenones

Pillay, M. Krishna,Palanivelu, S.

, p. 1055 - 1059 (2007/10/02)

The kinetics of oxidation of some mono-, di- and tri-substituted acetophenones by alkaline hexacyanoferrate(III) in 50percent (v/v) methanol-water mixture at constant ionic strength and at 20, 30 and 40 deg have been studied spectrophotometrically and the rate constants determined by least-squares analysis.Electron-withdrawing groups in the ring facilitate the oxidation of the acetyl function while electron-releasing groups retard the rate.The rate constant values for the oxidation of 3-substituted-4-alkoxy-acetophenones are computed based on the principle of additivity of group effects.The observed rate constants are significantly lower than the calculated values.This is attributed to the phenomenon of steric enhancement of resonance (SER). 3,5-Disubstituted-4-methoxyacetophenones have higher observed rate constant values than the calculated ones.The steric inhibition of resonance (SIR) operates in these systems.In the case of 3-halogeno-4-methoxyacetophenones, the importance of SER increases with increase in the bulkiness of the 3-substituents.The difference between the calculated and observed multiple substituent constants of 3-substituted-4-methoxyacetophenones also lends support for SER.
