Butyric acid, also known as butanoic acid, is a short-chain fatty acid with the chemical formula C4H8O2. It is a colorless, oily liquid with a strong, unpleasant odor reminiscent of rancid butter. Butyric acid is naturally produced in the body during the metabolism of dietary fibers and is also found in various foods, such as butter, parmesan cheese, and some fruits. Calcium butyrate, on the other hand, is the calcium salt of butyric acid, with the chemical formula C8H14CaO4. It is a white, crystalline powder that is soluble in water. Calcium butyrate is used as a dietary supplement and has potential health benefits, such as improving gut health and reducing the risk of certain diseases. Both butyric acid and calcium butyrate have applications in the food industry, pharmaceuticals, and as chemical intermediates in the synthesis of various compounds.
The CAS Registry Mumber 5892-23-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,9 and 2 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5892-23: (6*5)+(5*8)+(4*9)+(3*2)+(2*2)+(1*3)=119 119 % 10 = 9 So 5892-23-9 is a valid CAS Registry Number.
