Check Digit Verification of cas no
The CAS Registry Mumber 68227-69-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,2 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 68227-69:
(7*6)+(6*8)+(5*2)+(4*2)+(3*7)+(2*6)+(1*9)=150
150 % 10 = 0
So 68227-69-0 is a valid CAS Registry Number.

Catalysis of Sulfonate Ester Hydrolysis by Intramolecular Amide Group Assistance.

Kinetics of the alkaline hydrolysis of aryl 2-(acylamino)benzenesulfonates (1, X=OAr) obey the equation kobs=(Ka+kb->/(1++>/Ko).Hammett equations correlate the parameters ka, kb, and Ka for variation in both amido and leaving phenolate substituents.The values and sign of the ρ values together with entropy of activation data, reactivity trapping, and oxygen-18 incorporation are consistent with the formation of an intermediate benzoxathiazine S,S-dioxide (2).The ka term involves intramolecular attack of the amido anion.The kb term is consistent with a specific anion effect on ka.Regular bimolecular BAc2 mechanisms for ka and kb are not consistent with the high observed reactivity of these parameters.
