189749-40-4 Usage
General Description
1(3H)-Isobenzofuranone, 3,3-bis[4-[(methylsulfonyl)oxy]phenyl]-, also known by its trade name IMS, is a chemical compound used as a flame retardant in a variety of materials, including plastics, textiles, and electronics. It is a white, crystalline powder that is insoluble in water and most organic solvents. IMS has low volatility and high thermal stability, making it an effective additive for reducing the flammability of various materials. It works by releasing a non-combustible gas when exposed to high temperatures, effectively diluting the oxygen and preventing the material from catching fire. IMS is considered to be a relatively safe and effective flame retardant, and it is widely used in commercial and industrial applications.
Check Digit Verification of cas no
The CAS Registry Mumber 189749-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,7,4 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 189749-40:
(8*1)+(7*8)+(6*9)+(5*7)+(4*4)+(3*9)+(2*4)+(1*0)=204
204 % 10 = 4
So 189749-40-4 is a valid CAS Registry Number.
