1255-88-5 Usage
General Description
Cholestanol acetate, also known as 5α-cholestan-3β-ol acetate, is a sterol compound that is derived from cholesterol. It is a white, crystalline powder that is soluble in chloroform, ether, and benzene. Cholestanol acetate is used as a precursor in the synthesis of various steroidal compounds and hormones, as well as a reference standard for analytical testing. It is also used in research to study the metabolism and function of cholesterol in the body. Cholestanol acetate is an important chemical in the field of biochemistry and pharmaceutical research due to its role in the synthesis and study of steroidal compounds and hormones.
Check Digit Verification of cas no
The CAS Registry Mumber 1255-88-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1255-88:
(6*1)+(5*2)+(4*5)+(3*5)+(2*8)+(1*8)=75
75 % 10 = 5
So 1255-88-5 is a valid CAS Registry Number.

Photoreduction d'esters d'acides perfluores dans l'hexamethylphosphortriamide (HMPT). Elimination selective du fluor en α du groupe carboxyle
Portella, C.,Pete, J. P.
, p. 211 - 214 (2007/10/02)
The first example of fluorine elimination α to a carboxyl group is reported.The defluorination occurs when solution of perfluorocarboxylic esters in hexamethylphosphortriamide are irradiated with UV light (254 nm).Mechanistic and synthetic aspects of this new reaction are described.
