It is an important intermediate in the biosynthesis of various steroid hormones, including cortisol, aldosterone, and testosterone. 6-oxo-3α,5-cyclo-5α-cholestan-19-oic acid features a cycloalkane ring structure with a 6-oxo group, indicating the presence of a carbonyl group at the 6-position, and a 19-oic acid functional group, which is a carboxylic acid at the 19-position. The 3α,5-cyclo configuration refers to the specific arrangement of the carbon atoms at positions 3 and 5, which are part of the cycloalkane ring. This chemical plays a crucial role in the human body's endocrine system and is involved in various physiological processes, such as immune response, inflammation, and electrolyte balance.
The CAS Registry Mumber 3111-05-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,1 and 1 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3111-05: (6*3)+(5*1)+(4*1)+(3*1)+(2*0)+(1*5)=35 35 % 10 = 5 So 3111-05-5 is a valid CAS Registry Number.
