7,10,13,16-Docosatetraenoic acid, also known as arachidonic acid, is a polyunsaturated omega-6 fatty acid with a 20-carbon chain and four double bonds. It plays a crucial role in the human body, as it is a precursor to eicosanoids, which are hormone-like compounds involved in various physiological processes, including inflammation, blood clotting, and immune response. Arachidonic acid is primarily found in animal-based foods, such as meat, eggs, and fish, and is essential for maintaining proper brain function, as well as supporting growth and development. However, excessive consumption of arachidonic acid may lead to increased inflammation and potential health risks, so it is important to maintain a balanced diet with an appropriate ratio of omega-6 to omega-3 fatty acids.

Check Digit Verification of cas no

The CAS Registry Mumber 2091-25-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,9 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2091-25:
(6*2)+(5*0)+(4*9)+(3*1)+(2*2)+(1*5)=60
60 % 10 = 0
So 2091-25-0 is a valid CAS Registry Number.

Synthesis of C2-elongated polyunsaturated fatty acids

Kuklev,Popkov,Kas'yanov,Akulin,Bezuglov

, p. 192 - 195 (2007/10/03)

The synthesis by a modified malonic ester procedure of C2-elongated polyunsaturated fatty acids from their natural precursors was described. Using the suggested Scheme 1, (7Z,11Z,14Z)-7,11,14-eicosatrienoic, (8Z,11Z,14Z,17Z)-8,11,14,17-eicosatetraenoic, (5Z,8Z,11Z,14Z,17Z)-5,8,11,14,17-eicosapentaenoic, (8Z,11Z,14Z,17Z)-8,11,14,17-docosatetraenoic, (7Z,10Z,13Z,16Z,19Z)-7,10,13,16,19-docosapentaenoic, and (6Z,9Z,12Z,15Z,18Z,21Z)-6,9,12,15,18,21-tetracosahexaenoic acids were synthesized. Their structures were confirmed by GC, UV, and MS data, which coincided with those of natural compounds. The target compounds were shown to be free from by-products, which could result from Z-E isomerization or migration of double bonds. The overall yields of the four-step synthesis of C2-elongated polyenoic acids were 25-30%.
