Check Digit Verification of cas no
The CAS Registry Mumber 257952-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,9,5 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 257952-99:
(8*2)+(7*5)+(6*7)+(5*9)+(4*5)+(3*2)+(2*9)+(1*9)=191
191 % 10 = 1
So 257952-99-1 is a valid CAS Registry Number.

New synthetic method to 1,2-benzisothiazoline-3-one-1,1- dioxides and 1,2-benzisothiazoline-3-one-1-oxides from N-alkyl(o- methyl)arenesulfonamides

Various N-alkylsaccharins were easily prepared in moderate to good yields by the reaction of N-alkyl(o- methyl)arenesulfonamides with (diacetoxyiodo)benzene in the presence of iodine under irradiation with a tungsten lamp (W-hv). On the other hand, irradiation of N- alky](omethyl)arenesulfonamide derivatives bearing various substituents on the aromatic ring with a high-pressure mercury lamp (Hg-hv), in the presence of (diacetoxyiodo)benzene and iodine gave the corresponding N-alkyl-1,2-benzisothiazoline-3- one-1-oxide derivatives in moderate yields, together with N- alkyl-1,2-benzisothiazoline-3-one-1,1-dioxide (saccharin) derivatives.
