3971-35-5 Usage
General Description
4,4'-Sulfonylbis(benzoic acid butyl) ester, also known as bis(2-butylbenzofuran-3-yl) sulfone, is a chemical compound used primarily as a plasticizer in the production of various polymers and resins. It is a high molecular weight ester that provides flexibility and durability to plastic products, making it suitable for applications in the manufacturing of PVC, acrylics, and other thermoplastic materials. This chemical is also used as a flame retardant and heat stabilizer in electrical insulators, cables, and automotive components. Despite its useful properties, 4,4'-Sulfonylbis(benzoic acid butyl) ester may pose environmental and health risks, with potential concerns over its persistence, bioaccumulation, and toxicity. Therefore, it is important to handle and dispose of this chemical with caution and in accordance with applicable regulations.
Check Digit Verification of cas no
The CAS Registry Mumber 3971-35-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,7 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3971-35:
(6*3)+(5*9)+(4*7)+(3*1)+(2*3)+(1*5)=105
105 % 10 = 5
So 3971-35-5 is a valid CAS Registry Number.
