2,2,5,5-Tetrachloro-1,6-hexanedial, also known as chlorendic anhydride, is a chemical compound with the formula C6H4Cl4O2. It is a white crystalline solid that is widely used in the production of various polymers, such as polyvinyl chloride (PVC) and polyurethane. 2,2,5,5-tetrachloror-1,6-hexanedial is synthesized by the reaction of acetylene with tetrachloro-p-benzoquinone, and it serves as a versatile monomer in the polymer industry. Due to its chemical structure, it imparts flame retardant properties to the polymers it is used in, making it a valuable component in the production of materials with enhanced fire resistance.
The CAS Registry Mumber 76043-71-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,0,4 and 3 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 76043-71: (7*7)+(6*6)+(5*0)+(4*4)+(3*3)+(2*7)+(1*1)=125 125 % 10 = 5 So 76043-71-5 is a valid CAS Registry Number.
