ω-Chlor-perfluor-nonansaeure-(α,α,ω-trichlor-perfluor-nonylester) is a complex chemical compound with the molecular formula C9Cl15F13O2. It is a perfluorinated carboxylic acid derivative, characterized by the presence of a chlorinated perfluorononanoic acid group and a trichloroperfluorononyl ester group. ω-Chlor-perfluor-nonansaeure-(α,α,ω-trichlor-perfluor-nonylester) is known for its unique properties, such as high thermal stability, chemical resistance, and low surface tension, which make it useful in various industrial applications, including as a surfactant or a component in fire-fighting foams. Due to its perfluorinated nature, it is also associated with environmental concerns, as some perfluorinated compounds have been found to persist in the environment and accumulate in the food chain.
The CAS Registry Mumber 3918-10-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,1 and 8 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 3918-10: (6*3)+(5*9)+(4*1)+(3*8)+(2*1)+(1*0)=93 93 % 10 = 3 So 3918-10-3 is a valid CAS Registry Number.
