6328-72-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6328-72-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,2 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6328-72:
(6*6)+(5*3)+(4*2)+(3*8)+(2*7)+(1*2)=99
99 % 10 = 9
So 6328-72-9 is a valid CAS Registry Number.

Linear Free Energy Relationship in Naphthalene System: Kinetics of Hydrolysis of 4-Substituted 1-Naphthalenesulphonyl Chlorides

Perumal, S.,Selvaraj, S.,Viswanathan, T. K.,Arumugam, N.

, p. 436 - 438 (2007/10/02)

The kinetics of hydrolysis of several 4-substituted 1-naphthalenesulphonyl chlorides have been studied in aqueous acetone at three temperatures.The reaction is first order in sulphonyl chloride.Presence of electron-withdrawing substituents in the naphthyl ring enhances the rate while that of opposite ones retards it.The small ρ-values obtained in the correlation analysis using the Hammett and dual substituent parameter equations are consistent with either an SN2 or an SAN mechanism.
