5α-Cholest-1-en, also known as cholest-1-en-3β-ol or cholesterol, is a naturally occurring steroid compound that plays a crucial role in various biological processes. It is a waxy, white solid with the molecular formula C27H46O and a molecular weight of 386.66 g/mol. Cholesterol is an essential component of cell membranes, helping to maintain their fluidity and integrity. It is also a precursor for the synthesis of other important molecules, such as bile acids, vitamin D, and steroid hormones. In humans, cholesterol is primarily synthesized in the liver and is also obtained through the diet. While it is vital for maintaining overall health, high levels of cholesterol in the bloodstream can lead to the formation of plaques in the arteries, increasing the risk of cardiovascular diseases.
The CAS Registry Mumber 604-18-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 4 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 604-18: (5*6)+(4*0)+(3*4)+(2*1)+(1*8)=52 52 % 10 = 2 So 604-18-2 is a valid CAS Registry Number.
