C18H39O2P is a chemical compound with the molecular formula C18H39O2P, which consists of 18 carbon atoms, 39 hydrogen atoms, 2 oxygen atoms, and 1 phosphorus atom. C18H39O2P is a type of phospholipid, which is a major component of cell membranes. Phospholipids are amphiphilic molecules, meaning they have both hydrophilic (water-loving) and hydrophobic (water-fearing) regions. In the structure of C18H39O2P, the hydrophilic part is the phosphate group (PO4), while the hydrophobic part is the long hydrocarbon chain. These molecules arrange themselves in a bilayer within the cell membrane, with the hydrophilic heads facing the aqueous environments inside and outside the cell, and the hydrophobic tails facing each other, forming the interior of the membrane. This arrangement is crucial for the membrane's function in controlling the passage of substances in and out of the cell.
The CAS Registry Mumber 2071-55-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,7 and 1 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2071-55: (6*2)+(5*0)+(4*7)+(3*1)+(2*5)+(1*5)=58 58 % 10 = 8 So 2071-55-8 is a valid CAS Registry Number.
