160332-20-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 160332-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,3,3 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 160332-20:
(8*1)+(7*6)+(6*0)+(5*3)+(4*3)+(3*2)+(2*2)+(1*0)=87
87 % 10 = 7
So 160332-20-7 is a valid CAS Registry Number.

Method for preparing chiral (1R,2S)-1-phenyl-2-(1-pyrrolidyl)propane-1-alcohol

-

Page/Page column 0037-0042, (2019/01/23)

The invention provides a new method for simply and feasibly synthesizing (1R,2S)-1-phenyl-2-(1-pyrrolidyl)propane-1-alcohol through enzymatic catalysis. The method is easy to operate and mild in condition, an intermediate does not need to be separated, th

Chemoenzymatic synthesis of chiral epoxides. Preparation of 4-phenyl-2,3- epoxybutane and 1-phenyl-1,2-epoxypropane

Besse,Renard,Veschambre

, p. 1249 - 1268 (2007/10/02)

All the stereoisomers of 4-phenyl-2,3-epoxybutane and 1-phenyl-1,2- epoxypropane (β-methylstyrene oxide) have been prepared in three steps from 4-phenyl-2-butanone and 1-phenyl-2-propanone or 1-phenyl-1-propanone respectively. The key step is the microbiological reduction of the corresponding haloketones. These results confirm those previously described and demonstrate that the chemoenzymatic synthesis of homochiral 2,3-epoxides is a general method that can be used whatever the starting ketone.
