3-Chlor-2-methyl-1,2-benzisothiazoliumchlorid, also known as CMIT or MCIT, is a chemical compound with the molecular formula C8H6ClN3S2. It is a halogenated derivative of 1,2-benzisothiazolium chloride, which is a heterocyclic compound containing a benzene ring fused to an isothiazolium ring. 3-Chlor-2-methyl-1,2-benzisothiazoliumchlorid is widely used as a biocide, particularly in industrial water treatment systems, to control the growth of microorganisms such as bacteria, algae, and fungi. It is effective at low concentrations and is known for its broad-spectrum activity. Due to its chemical structure, it can disrupt the cell membranes of microorganisms, leading to their inactivation. However, its use is subject to regulatory controls to ensure environmental and human safety, as it can be toxic to aquatic life and requires proper handling and disposal.
The CAS Registry Mumber 4163-05-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,6 and 3 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 4163-05: (6*4)+(5*1)+(4*6)+(3*3)+(2*0)+(1*5)=67 67 % 10 = 7 So 4163-05-7 is a valid CAS Registry Number.
