777851-20-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 777851-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,7,8,5 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 777851-20:
(8*7)+(7*7)+(6*7)+(5*8)+(4*5)+(3*1)+(2*2)+(1*0)=214
214 % 10 = 4
So 777851-20-4 is a valid CAS Registry Number.

Structure-activity considerations in kinetics and mechanism of chlorine exchange between chloramine-T and secondary amines

Dannan,Hussain,Crooks,Dittert

, p. 657 - 660 (1992)

To study the mechanism of N-chlorination of secondary amines by chloramine-T, the kinetics of the reactions of some aromatic-substituted analogues of N-chlorobenzenesulfonamide with various secondary amines were determined. The importance of amine basicity and reactivity of the N-Cl bond of the N-chlorobenzenesulfonamide was also assessed. The results indicate that a mechanism involving the un-ionized species of both reactants (i.e., a molecular mechanism), rather than an ionic mechanism, is operating and that the reaction most likely proceeds via a six-membered-ring transition state that incorporates a water molecule.
