Acetic acid 5-chloro-6β-nitro-5α-cholestan-3β-yl ester is a complex organic compound with the chemical formula C28H45ClNO4. It is derived from acetic acid, where the hydroxyl group is replaced by a 5-chloro-6β-nitro-5α-cholestan-3β-yl group. This molecule features a cholesterol-like structure with a 5α-cholestan core, which is modified by the addition of a 5-chloro and 6β-nitro group. The ester linkage with acetic acid provides a carboxylic acid functional group, enhancing the molecule's reactivity and solubility properties. Acetic acid 5-chloro-6β-nitro-5α-cholestan-3β-yl ester is typically synthesized for research purposes, particularly in the fields of organic chemistry and pharmaceuticals, where it may be used to study the effects of structural modifications on biological activity or as a potential intermediate in the synthesis of more complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 1431-22-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,3 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1431-22:
(6*1)+(5*4)+(4*3)+(3*1)+(2*2)+(1*2)=47
47 % 10 = 7
So 1431-22-7 is a valid CAS Registry Number.
