3α-hydroxy-24-nor-5α-cholanoic acid-(23) is a naturally occurring steroidal compound, derived from cholesterol, and is characterized by the presence of a hydroxyl group at the 3α position, the absence of a carbon atom at the 24th position (hence the term "nor"), and the presence of a carboxylic acid group at the 23rd position. 3α-hydroxy-24-nor-5α-cholanoic acid-(23) is part of the bile acid family, which plays a crucial role in the digestion and absorption of dietary fats. It is synthesized in the liver and is involved in the emulsification of fats, making them more accessible for enzymatic breakdown and absorption in the small intestine. The structure of this bile acid is distinct due to the lack of a carbon atom at the 24th position, which can influence its physicochemical properties and biological activities compared to other bile acids.
The CAS Registry Mumber 4057-89-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,5 and 7 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4057-89: (6*4)+(5*0)+(4*5)+(3*7)+(2*8)+(1*9)=90 90 % 10 = 0 So 4057-89-0 is a valid CAS Registry Number.
