4,4-dimethyl-5α-cholestan-2α-ol, also known as lanosterol, is a naturally occurring sterol and a key intermediate in the biosynthesis of cholesterol. It is a 3β-hydroxy-4α-methyl sterol with a molecular formula of C30H50O and a molecular weight of 426.72 g/mol. Lanosterol plays a crucial role in the conversion of squalene to cholesterol through a series of enzymatic reactions. It is found in various organisms, including plants, animals, and fungi, and is an essential component in the cell membrane structure. Due to its importance in cholesterol synthesis, lanosterol has been a subject of interest in the development of drugs targeting cholesterol metabolism for the treatment of hypercholesterolemia and other related diseases.
The CAS Registry Mumber 808-30-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,0 and 8 respectively; the second part has 2 digits, 3 and 0 respectively. Calculate Digit Verification of CAS Registry Number 808-30: (5*8)+(4*0)+(3*8)+(2*3)+(1*0)=70 70 % 10 = 0 So 808-30-0 is a valid CAS Registry Number.
