General Description
4,4-Diiododiphenylsulfone is a chemical compound with the formula C12H8I2O2S. It is a sulfone derivative that consists of a diphenylsulfone molecule with iodine atoms at the 4,4 positions. 4,4-Diiododiphenylsulfone is used in the production of high-performance polymers, particularly for applications requiring high thermal stability and chemical resistance. It is commonly used as a building block in the synthesis of poly(aryl ether sulfone) and poly(aryl ether ketone) polymers, which find uses in aerospace, automotive, and electronics industries. 4,4-Diiododiphenylsulfone is also known to have antibacterial and antifungal properties, making it potentially valuable in medical and healthcare applications. However, its toxicity and environmental impact should be taken into consideration when handling and disposing of this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 40915-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,1 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40915-22:
(7*4)+(6*0)+(5*9)+(4*1)+(3*5)+(2*2)+(1*2)=98
98 % 10 = 8
So 40915-22-8 is a valid CAS Registry Number.
