109439-90-9 Usage
General Description
1,2-DIMETHYL-1H-BENZOTRIAZOLIUM IODIDE is a chemical compound that is commonly used as a photoinitiator in polymerization reactions. It is a stable and efficient photoinitiator that is used in the UV-curing industry to initiate the polymerization of various monomers and oligomers. 1,2-DIMETHYL-1H-BENZOTRIAZOLIUM IODIDE has a high absorption in the UV range, which allows it to effectively initiate the curing process of polymer materials. It is also used as a corrosion inhibitor in industrial applications and as an intermediate in the synthesis of pharmaceuticals and dyes. 1,2-DIMETHYL-1H-BENZOTRIAZOLIUM IODIDE is typically handled and stored in a dry and well-ventilated area, away from heat and sources of ignition, as it may be flammable under certain conditions.
Check Digit Verification of cas no
The CAS Registry Mumber 109439-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,3 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109439-90:
(8*1)+(7*0)+(6*9)+(5*4)+(4*3)+(3*9)+(2*9)+(1*0)=139
139 % 10 = 9
So 109439-90-9 is a valid CAS Registry Number.
