91190-75-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91190-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,9 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91190-75:
(7*9)+(6*1)+(5*1)+(4*9)+(3*0)+(2*7)+(1*5)=129
129 % 10 = 9
So 91190-75-9 is a valid CAS Registry Number.

Intramolecular Nucleophilic Catalysis by the Neighboring Hydroxyl Group in Acid-Catalyzed Benzenesulfonamide Hydrolysis

Wagenaar, Anno,Kirby, Anthony J.,Engberts, Jan B. F. N.

, p. 3445 - 3448 (2007/10/02)

The reactivity towards the neighboring hydroxyl group of two N,N-dialkylbenzenesulfonamide systems 1 and 2 is extraordinarily sensitive to structure.In the presence of o-CH2OH, the SO2NMe2 group is stable almost indefinitely in 1 M HCl, whereas the corresponding compound with o-CMe2OH cyclizes to the sultone under the same conditions with a half-life of around 20 min.When the sulfonamide group is constrained in a five-membered ring its cleavage must be followed by the stopped-flow technique.These very large variations in reactivity are interpreted primarily in termsof ground-state strain, which is partially relieved in the transition state for cyclization.
