2-Hydroxy-3-methoxy-5-methyl-6-phytyl-1,4-benzochinon, also known as vitamin K1 or phylloquinone, is a fat-soluble vitamin that plays a crucial role in blood clotting and bone metabolism. This chemical compound consists of a 1,4-benzoquinone ring with a 2-hydroxy group, a 3-methoxy group, a 5-methyl group, and a 6-phytyl side chain. The phytyl side chain is a 20-carbon isoprenoid chain derived from plant chlorophyll, which contributes to the vitamin's lipophilic nature. Vitamin K1 is primarily found in green leafy vegetables and is essential for the synthesis of proteins involved in blood coagulation, such as prothrombin, and for maintaining bone health by regulating the activity of osteocalcin. A deficiency in vitamin K1 can lead to bleeding disorders and weakened bones, while excessive intake can cause toxicity.
The CAS Registry Mumber 2819-32-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,1 and 9 respectively; the second part has 2 digits, 3 and 2 respectively. Calculate Digit Verification of CAS Registry Number 2819-32: (6*2)+(5*8)+(4*1)+(3*9)+(2*3)+(1*2)=91 91 % 10 = 1 So 2819-32-1 is a valid CAS Registry Number.
