Check Digit Verification of cas no

The CAS Registry Mumber 77826-10-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,2 and 6 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77826-10:
(7*7)+(6*7)+(5*8)+(4*2)+(3*6)+(2*1)+(1*0)=159
159 % 10 = 9
So 77826-10-9 is a valid CAS Registry Number.

Micellar Catalysis of the Basic Hydrolysis of Amides. 4. Substituted N,N-Diphenylbenzamides

Broxton, Trevor J.,Fernando, Denise R.,Rowe, Jeffrey E.

, p. 3522 - 3525 (2007/10/02)

The cytalysis of the basic hydrolysis of a series of N-aryl-N-phenylbenzamides (1) and a series of substituted N,N-diphenylbenzamides (2) by micelles of cetyltrimethylammonium bromide (ctab) has been studied.On the basis of the effects of substituents on the aromatic ring attached to the nitrogen atom, a mechanistic change on transfer from water to a micellar environment is proposed.In water the mechanism involves rate-determining solvent-assisted carbon-nitrogen bond breaking (mechanism B), while in the presence of micelles of ctab, a rate-determining attack of hydroxide ion (mechanism C) is proposed.Reasons for mechanistic change are discussed.
