5-beta-cholestan-3-beta-yl acetate, also known as cholestanol acetate, is a chemical compound derived from cholestanol, a naturally occurring steroid alcohol. It is characterized by a cholestane ring structure with a hydroxyl group at the 3-beta position and an acetate group at the 5-beta position. 5-beta-cholestan-3-beta-yl acetate is used as a reference standard in various analytical techniques, such as gas chromatography and mass spectrometry, for the identification and quantification of cholesterol and its metabolites in biological samples. Cholestanol acetate serves as an internal standard, helping to account for variations in sample preparation and instrument performance, thus ensuring accurate and reliable results in the analysis of cholesterol-related compounds.
The CAS Registry Mumber 4947-63-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,4 and 7 respectively; the second part has 2 digits, 6 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4947-63: (6*4)+(5*9)+(4*4)+(3*7)+(2*6)+(1*3)=121 121 % 10 = 1 So 4947-63-1 is a valid CAS Registry Number.
