ω-Chlor-perfluor-heptansaeure-(α,α,ω-trichlor-perfluor-heptylester), also known as C12F23Cl3O2, is a complex organic compound belonging to the family of perfluorinated chemicals. It is characterized by a perfluorinated heptyl chain with three chlorine atoms attached to the terminal carbon (ω-position) and an additional chlorine atom at the α-position of the heptyl chain. This molecule is an ester, formed by the reaction of ω-chloroperfluoroheptanoic acid with α,α,ω-trichloro-perfluoroheptyl alcohol. Due to its unique structure, it exhibits properties such as high chemical stability, low surface tension, and resistance to degradation, which are commonly associated with perfluorinated compounds. These characteristics make it useful in various industrial applications, including as a surfactant or in the production of specialized coatings. However, due to concerns over the environmental persistence and potential health impacts of perfluorinated chemicals, there is ongoing research and regulation surrounding their use.

1691-29-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1691-29-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,9 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1691-29:
(6*1)+(5*6)+(4*9)+(3*1)+(2*2)+(1*9)=88
88 % 10 = 8
So 1691-29-8 is a valid CAS Registry Number.
