General Description
1,2-Benzisothiazol-3(2H)-one,2-ethyl-5-methyl-,1-oxide(9CI) is a chemical compound with the molecular formula C10H11NOS. It is commonly known as BIT or benzisothiazolinone. It is a heterocyclic compound and is widely used as a biocide and preservative in various industrial and consumer products, including personal care products, paints, and adhesives. BIT is known for its antimicrobial properties and is effective against a wide range of bacteria, fungi, and algae. However, it is also known to be a potential skin sensitizing agent and has been associated with allergic reactions in some individuals. As a result, its use is regulated in some countries, and it is important for individuals to be aware of its presence in products to avoid potential allergic reactions.
Check Digit Verification of cas no
The CAS Registry Mumber 257953-00-7 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 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 257953-00:
(8*2)+(7*5)+(6*7)+(5*9)+(4*5)+(3*3)+(2*0)+(1*0)=167
167 % 10 = 7
So 257953-00-7 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.
