General Description
"(3a,5b,6a,12a)-3,6,12-trihydroxy-Cholan-24-oic acid" is a chemical compound that belongs to the class of cholic acids, which are important components of bile. This specific compound has a steroid structure and contains three hydroxyl (OH) groups at the 3, 6, and 12 positions on the molecule. It is an important component in the digestion and absorption of fats in the body, as bile acids help to emulsify lipids and aid in their absorption in the intestines. Additionally, cholic acids play a role in the regulation of cholesterol and lipid metabolism. This specific compound, with its unique hydroxyl arrangement, likely plays a crucial role in these physiological processes.
Check Digit Verification of cas no
The CAS Registry Mumber 21066-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,6 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21066-18:
(7*2)+(6*1)+(5*0)+(4*6)+(3*6)+(2*1)+(1*8)=72
72 % 10 = 2
So 21066-18-2 is a valid CAS Registry Number.
