B-Nor-5β-cholestan-3-one, also known as 5β-cholestan-3-one, is a steroidal ketone derived from the cholesterol molecule. It is characterized by the absence of a carbon atom at position B (the second carbon atom), which results in a nor (short for norbornane) structure. B-Nor-5β-cholestanon-(3) is of interest in the field of organic chemistry and biochemistry, particularly in studies related to steroid metabolism and the synthesis of various steroidal compounds. It is also used as an intermediate in the preparation of other complex steroidal molecules. The structure of B-Nor-5β-cholestan-3-one features a ketone group at the C-3 position and a 5β-hydrogen configuration, which influences its chemical properties and reactivity.

2449-95-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2449-95-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,4 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.Calculate Digit Verification of CAS Registry Number 2449-95:
(6*2)+(5*4)+(4*4)+(3*9)+(2*9)+(1*5)=98
98 % 10 = 8
So 2449-95-8 is a valid CAS Registry Number.
