Check Digit Verification of cas no

The CAS Registry Mumber 27460-26-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,4,6 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 27460-26:
(7*2)+(6*7)+(5*4)+(4*6)+(3*0)+(2*2)+(1*6)=110
110 % 10 = 0
So 27460-26-0 is a valid CAS Registry Number.

A highly stereoselective synthesis of C-24 and C-25 oxysterols from desmosterol

Zhao, Qian,Qian, Chao,Chen, Xin-Zhi

, p. 16 - 21 (2016)

A new highly stereoselective construction of the side chain of the C-24 and C-25 oxysterols has been achieved by using desmosterol acetate as the starting material and an improved Sharpless catalytic asymmetric dihydroxylation with 100% d.e. (diastereomeric excess) as the key step. The result is much better than the usual asymmetric dihydroxylation procedure. t-Butyl nitrite/2,2,6,6-tetramethylpiperidine N-oxyl radical/FeCl3 catalyst system was developed to activate molecular oxygen for the aerobic oxidation of 24-hydroxycholesterol and the 24-ketocholesterol was obtained in 86.2% yield. The oxidation system has never been reported before. The mechanism for the catalytic aerobic oxidation was also proposed.

A Stereoselective Synthesis and a Convenient Synthesis of Optically Pure (24 R)- and (24 S)-24-hydroxycholesterols

Koch, Patrick,Nakatani, Yoichi,Luu, Bang,Ourisson, Guy

, p. 185 - 194 (2007/10/02)

A new stereoselective synthesis of optically pure (24 S)-24-hydroxycholesterol (cerebrosterol) and (24 R)-24-hydroxycholesterol, using D- and L-valines as chiral sources, as well as a convenient synthesis, are described.
