(9Z,12Z)-Octadeca-9,12-dienoate, also known as linoleic acid, is a polyunsaturated omega-6 fatty acid with the molecular formula C18H32O2. It is an essential fatty acid, meaning that it cannot be synthesized by the human body and must be obtained through diet. Linoleic acid plays a crucial role in various physiological processes, including cell membrane structure, inflammation regulation, and skin health. It is commonly found in plant-based oils, such as sunflower, safflower, and corn oil, as well as in nuts and seeds. Due to its double bonds, linoleic acid is prone to oxidation, which can lead to the formation of harmful compounds; therefore, it is important to consume it in moderation and store it properly to maintain its nutritional benefits.

Check Digit Verification of cas no

The CAS Registry Mumber 1509-85-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,0 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1509-85:
(6*1)+(5*5)+(4*0)+(3*9)+(2*8)+(1*5)=79
79 % 10 = 9
So 1509-85-9 is a valid CAS Registry Number.

Additivity rule holds in the hydrogen transfer reactivity of unsaturated fatty acids with a peroxyl radical: Mechanistic insight into lipoxygenase

Kitaguchi, Hironori,Ohkubo, Kei,Ogo, Seiji,Fukuzumi, Shunichi

, p. 979 - 981 (2008/02/03)

A simple additivity rule holds in the hydrogen transfer reactivity of unsaturated fatty acids with cumylperoxyl radical, which is expressed by the additive contributions of the reactivity of active hydrogens from the 1,4-pentadiene subunit and those of the allylic subunit; the kinetic isotope effect on the hydrogen transfer reactions (KIE = 6.1) is significantly smaller than that observed for lipoxygenase (KIE = 81).
