Tris-(p-chlorophenyl)butyltin, also known as TCPB, is an organotin compound with the chemical formula C24H21Cl3Sn. It is a white crystalline solid that is insoluble in water but soluble in organic solvents. TCPB is primarily used as a catalyst in the production of polyurethane foams and as a heat stabilizer in PVC plastics. Due to its potential environmental and health risks, including endocrine disruption and aquatic toxicity, its use has been restricted or banned in several countries. The compound is also known for its biocidal properties, making it effective against various microorganisms, but these characteristics have led to concerns about its persistence and bioaccumulation in the environment.

Check Digit Verification of cas no

The CAS Registry Mumber 82593-99-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,5,9 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82593-99:
(7*8)+(6*2)+(5*5)+(4*9)+(3*3)+(2*9)+(1*9)=165
165 % 10 = 5
So 82593-99-5 is a valid CAS Registry Number.
