61262-80-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 61262-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,2,6 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 61262-80:
(7*6)+(6*1)+(5*2)+(4*6)+(3*2)+(2*8)+(1*0)=104
104 % 10 = 4
So 61262-80-4 is a valid CAS Registry Number.

Lipase-catalyzed resolution of p-menthan-3-ols monoterpenes: Preparation of the enantiomer-enriched forms of menthol, isopulegol, trans- and cis-piperitol, and cis-isopiperitenol

Serra, Stefano,Brenna, Elisabetta,Fuganti, Claudio,Maggioni, Francesco

, p. 3313 - 3319 (2007/10/03)

A study on the enzymic resolution of the most common p-menthan-3-ol monoterpene isomers is described. Enantioenriched alcohols 1, 5, 10, 11 and 12 are obtained by means of the lipase-mediated kinetic acetylation of the corresponding racemic materials. The stereochemical aspects of the enzymic process have been investigated. We found that the structural features of the starting p-menthan-3-ol as well as the kind of lipase used, impacted strongly on the enantioselectivity of the resolution. The potentialities of this approach for preparative purposes are discussed.
