Lanostan-3α-ol, also known as lanosterol, is a naturally occurring steroid alcohol and a key intermediate in the biosynthesis of cholesterol and other steroids. It is a triterpenoid with a molecular formula of C30H50O and is found in various plants, fungi, and animals. Lanostan-3α-ol plays a crucial role in the mevalonate pathway, which is essential for the production of cholesterol, steroid hormones, and bile acids. Due to its importance in cholesterol synthesis, lanosterol has been a subject of interest in the development of drugs targeting cholesterol metabolism and related diseases.
The CAS Registry Mumber 6721-21-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,2 and 1 respectively; the second part has 2 digits, 2 and 1 respectively. Calculate Digit Verification of CAS Registry Number 6721-21: (6*6)+(5*7)+(4*2)+(3*1)+(2*2)+(1*1)=87 87 % 10 = 7 So 6721-21-7 is a valid CAS Registry Number.
