Eicosa-5,8,11,14-tetrayn-1-ol, also known as arachidonic acid, is a polyunsaturated omega-6 fatty acid with a 20-carbon chain and four double bonds. It is an essential fatty acid, meaning it must be obtained through diet as the human body cannot synthesize it. Arachidonic acid plays a crucial role in various physiological processes, including cell membrane structure, inflammation, and blood clotting. It is primarily found in animal-based foods such as meat, eggs, and dairy products, and is also present in some plant-based oils like soybean and corn oil. Due to its involvement in inflammation, arachidonic acid is a precursor to eicosanoids, which are signaling molecules that regulate immune responses and other physiological functions.
The CAS Registry Mumber 4184-96-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,8 and 4 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 4184-96: (6*4)+(5*1)+(4*8)+(3*4)+(2*9)+(1*6)=97 97 % 10 = 7 So 4184-96-7 is a valid CAS Registry Number.
