Octadeca-5,8-dienoic acid, also known as linoleic acid, is a polyunsaturated omega-6 fatty acid with an 18-carbon chain and two double bonds at the 5th and 8th carbon positions. 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 energy production. 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 health benefits, linoleic acid is often used as a dietary supplement and is considered an important component in maintaining overall health and well-being.

2197-50-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2197-50-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.Calculate Digit Verification of CAS Registry Number 2197-50:
(6*2)+(5*1)+(4*9)+(3*7)+(2*5)+(1*0)=84
84 % 10 = 4
So 2197-50-4 is a valid CAS Registry Number.
