General Description
(S)-(+)-3-Methyl-1-Pentanol is a chiral organic compound that exists as a colorless liquid. It's classified in the family of secondary alcohols, indicating that the hydroxyl functional group (-OH) is attached to a secondary carbon in the five-carbon main chain. This 3-Methyl-1-pentanol compound contains one chiral center that gives rise to enantiomerically pure forms, including the (S)-(+)-3-Methyl-1-Pentanol. The (+) designation elucidates that it's an optically active isomer that rotates plane-polarized light in a clockwise direction. It's utilized in various applications, primarily in flavorings and fragrances because of its flowery odor. However, proper handling is required as it may cause skin, eye, and respiratory tract irritation, as well as negative environmental impact if not managed properly.
Check Digit Verification of cas no
The CAS Registry Mumber 42072-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,7 and 2 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 42072-39:
(7*4)+(6*2)+(5*0)+(4*7)+(3*2)+(2*3)+(1*9)=89
89 % 10 = 9
So 42072-39-9 is a valid CAS Registry Number.

A SYNTHETIC APPROACH TO CHIRAL ACETYLENE DERIVATIVES FROM OPTICALLY ACTIVE ALDEHYDES
Marcacci, Fabrizio,Giacomelli, Giampaolo,Menicagli, Rita
, p. 195 - 200 (2007/10/02)
The applicability of some Wittig-type reactions for preparing optically active 1-alkynes and 3-alkylbutenynes from chiral aldehydes and 2-alkylacrylaldehydes, respectively, has been studied.The stereospecificity of the reactions has been evaluated and on the basis of the overall results, a satisfactory method for obtaining chiral 3-alkylbutenynes is suggested.
