Check Digit Verification of cas no
The CAS Registry Mumber 41480-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,4,8 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 41480-05:
(7*4)+(6*1)+(5*4)+(4*8)+(3*0)+(2*0)+(1*5)=91
91 % 10 = 1
So 41480-05-1 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.
