Check Digit Verification of cas no

The CAS Registry Mumber 143399-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,9 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143399-01:
(8*1)+(7*4)+(6*3)+(5*3)+(4*9)+(3*9)+(2*0)+(1*1)=133
133 % 10 = 3
So 143399-01-3 is a valid CAS Registry Number.

The first total synthesis of eudistomin Y7 (7) and total syntheses of eudistomins Y1-Y6 (1-6) are described. An efficient room-temperature conversion of 1-benzyl-3,4-dihydro-β-carbolines (11) into 1-benzoyl-β-carbolines (14) by a one-pot process of tandem benzylic oxidation and aromatization as the key step of these total syntheses was also studied in detail.

Enantioselective synthesis of binaphthyl polymers using chiral asymmetric phenolic coupling catalysts: Oxidative coupling and tandem glaser/oxidative coupling

Morgan, Barbara J.,Xie, Xu,Phuan, Puay-Wah,Kozlowski, Marisa C.

, p. 6171 - 6182 (2008/02/10)

(Chemical Equation Presented) A series of functionalized and optically active polybinaphthyls have been synthesized from achiral substrates by asymmetric oxidative phenolic coupling using a chiral 1,5-diaza-cis-decalin copper catalyst. In most cases, a copper tetrafluoroborate catalyst was found to be superior to the copper iodide catalyst, as ortho-iodination of the substrates could be prevented. Three methods for the formation of chiral polymers are described. In the first method, two 2-naphthols linked together at C-6 are subjected to the optimized asymmetric oxidative phenolic coupling conditions to form chiral polynaphthyls. A combination of NMR and HPLC measurements secured the selectivity of the asymmetric coupling. In the second method, substrates containing only one naphthalene were utilized. By incorporating a 2-naphthol and a terminal alkyne, the chiral copper catalysts effect both Glaser-Hay coupling of the alkyne and oxidative asymmetric coupling of the 2-naphthol with remarkable chemoselectivity. The relative reaction rates of various moieties with the chiral catalysts follows the order: benzyl cyanides ? aryl alkynes > electron-rich 2-naphthols > electron-deficient 2-naphthols > alkyl alkynes. Because of high chemoselectivity, this approach is useful for the organized assembly of multifunctional substrates in a single operation. In all cases, no cross-coupling is observed between the alkyne and the 2-naphthol. This approach was thus applied to a set of highly functionalized precursors. In this third case, the biaryl coupling was performed first and a Glaser-Hay coupling was performed in a separate step to generate a highly functionalized polymer. In some cases, the resultant chiral polymers exhibit very large optical rotations.
