Check Digit Verification of cas no

The CAS Registry Mumber 501657-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,6,5 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 501657-49:
(8*5)+(7*0)+(6*1)+(5*6)+(4*5)+(3*7)+(2*4)+(1*9)=134
134 % 10 = 4
So 501657-49-4 is a valid CAS Registry Number.

Palladium-catalyzed asymmetric allylic alkylation of α-aryl ketones

Trost, Barry M.,Schroeder, Gretchen M.,Kristensen, Jesper

, p. 3492 - 3495 (2002)

Quaternary centers can be created asymmetrically in high enantiomeric excess by the proper choice of ligand and metal cation in the Pd-catalyzed asymmetric allylic alkylation of α-aryl ketones. A broad range of ketone enolates can be tolerated in the reac

Enantioselective synthesis of rigid 2-aminotetralins. Utility of silicon as an oxygen and nitrogen surrogate in the tandem addition reaction

Degnan, Andrew P.,Meyers

, p. 3503 - 3512 (2007/10/03)

Dimethylphenylsilyllithium undergoes a highly diastereoselective conjugate addition to chiral naphthyloxazoline 11. Electrophilic trapping of the resulting aza-enolate affords the tandem addition product (12) in high yields as a single diastereomer. The silicon, thus incorporated, may be protodesilylated and undergoes a Tamao oxidation to afford the corresponding alcohol. By chemical modification of the oxazoline, both the γ-lactone (28) and the δ-lactone (37) were prepared. Reduction of each lactone followed by oxidation of the ensuing diol gave the keto aldehyde. Double reductive animation of the 1,4-dicarbonyl (from the γ-lactone) allowed the synthesis of two novel hexahydrobenz[e]indoles, 20 and 35. Double reductive amination of the 1,5-dicarbonyl (from the δ-lactone) gave access to two novel octahydrobenzo[f]quinolines, 41 and 43. An unprecedented rearrangement of nitro alcohol 26 into lactone 28 is described and a reasonable mechanism for its formation postulated.
