Spirostan is a class of naturally occurring steroidal compounds characterized by a spiro ring system, which consists of a five-membered and a six-membered ring fused together. These compounds are derived from plants, particularly from the Solanaceae and Liliaceae families, and exhibit a wide range of biological activities, including anti-inflammatory, anti-cancer, and immunosuppressive properties. Spirostanols, a subgroup of spirostan compounds, are known for their cholesterol-lowering effects and potential use in the treatment of hypercholesterolemia. The unique structure and diverse pharmacological properties of spirostan compounds make them an important area of research in the field of natural product chemistry and drug discovery.
The CAS Registry Mumber 511-93-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 1 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 511-93: (5*5)+(4*1)+(3*1)+(2*9)+(1*3)=53 53 % 10 = 3 So 511-93-3 is a valid CAS Registry Number.
