25887-81-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25887-81-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,8 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25887-81:
(7*2)+(6*5)+(5*8)+(4*8)+(3*7)+(2*8)+(1*1)=154
154 % 10 = 4
So 25887-81-4 is a valid CAS Registry Number.

A PROTON INVENTORY STUDY OF THE WATER-CATALYSED HYDROLYSIS OF A SULPHITE ESTER IN AQUEOUS DIOXANE

Selwood, Trevor,Tillett, John G.

, p. 55 - 60 (2007/10/02)

The water-catalysed (spontaneous) hydrolysis of bis(p-nitrophenyl) sulphite in aqueous dioxane exhibits a solvent deuterium isotope effect of kH2O/kD2O = 3.21 and is second order in water concentration.The proton inventory plot for mixtures of protium oxide-deuterium oxide shows significant downward curvature and suggests the involvement of three equivalent protons.Several possible transition states are considered.Key words: Proton inventory; sulphite ester hydrolysis
