289909-49-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 289909-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,9,0 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 289909-49:
(8*2)+(7*8)+(6*9)+(5*9)+(4*0)+(3*9)+(2*4)+(1*9)=215
215 % 10 = 5
So 289909-49-5 is a valid CAS Registry Number.

Stereocontrolled formation of amino acids and N-heterocycles bearing a quaternary chiral carbon

Roy, Stephanie,Spino, Claude

, p. 939 - 942 (2007/10/03)

Stereocontrolled formation of tertiary or quaternary chiral carbons bearing nitrogen was achieved using the [3,3]-sigmatropic rearrangement of cyanate to isocyanate as a key element. A short and highly selective sequence of reactions, starting from p-ment

p-menthane-3-carboxaldehyde: A useful chiral auxiliary for the synthesis of chiral quaternary carbons of high enantiomeric purity

Spino, Claude,Godbout, Cedrickx,Beaulieu, Christian,Harter, Magali,Mwene-Mbeja, Topwe M.,Boisvert, Luc

, p. 13312 - 13319 (2007/10/03)

(+)- or (-)-p-Menthane-S-carboxaldehyde is made in two easy steps from (+)- or (-)-menthone, respectively. This auxiliary allows for the synthesis of carbonyl compounds bearing a α-chiral quaternary carbon. The flexibility, efficiency, and ease of use of

Increased Felkin-Anh Selectivity Using AlMe3 in the Addition of Vinyllithiums to α-Chiral Aldehydes: Do "Ate" Complexes Play Any Role?

Spino, Claude,Granger, Marie-Claude,Tremblay, Marie-Claude

, p. 4735 - 4737 (2007/10/03)

(Matrix Presented) AlMe3 dramatically increases the diastereoselectivity of addition of vinyllithiums to α-chiral aldehydes but decreases that of methyllithium. Our results are explained in terms of an addition of the free vinyllithium on the M
