135413-42-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 135413-42-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,4,1 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 135413-42:
(8*1)+(7*3)+(6*5)+(5*4)+(4*1)+(3*3)+(2*4)+(1*2)=102
102 % 10 = 2
So 135413-42-2 is a valid CAS Registry Number.

Stereoselective conversion of campholene- to necrodane-type monoterpenes. Novel access to (-)-(R,R)- and (R,S)-α-Necrodol and the Enantiomeric γ-Necrodols

Pamingle, Herve,Snowden, Roger L.,Schulte-Elk, Karl H.

, p. 543 - 548 (1991)

Naturally occurring (-)-(R,R)-α -necrodol ((-)-1) and its C(4)-epimer (-)-2 are obtained in 84 and 44% yields, respectively, by lithium ethylenediamide (LEDA) treatment of the corresponding β-necrodols (-)-3 and (-)-4 (Scheme I , Table), both readily available from (-)-campholenyl acetate ((-)-i) by an efficient stereoselective synthesis. The thermodynamically preferred (-)-(R)-y -necrodol ((-)-5) becomes the major product ( ≥ 80 % yield) after either prolonged treatment with LEDA or exposure of α- and β-necrodols to BF3Et2O. In an alternative route, (+)-5 is prepared starting from (+)-campholenal ((+)-ii) via Pd-catalysed decarbonylation to (-)-(S)-1,4,5,5-tetramethylcyclopent-1-ene ((-)-6) and subsequent application of an acid-catalysed CH2O-addition/ rearrangement sequence (Scheme 2).
