Check Digit Verification of cas no

The CAS Registry Mumber 1052183-73-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,2,1,8 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1052183-73:
(9*1)+(8*0)+(7*5)+(6*2)+(5*1)+(4*8)+(3*3)+(2*7)+(1*3)=119
119 % 10 = 9
So 1052183-73-9 is a valid CAS Registry Number.

Highly Enantioselective Michael Addition of Nitroalkanes to Enones and Its Application in Syntheses of (R)-Baclofen and (R)-Phenibut

Guo, Xing-Tao,Shen, Jie,Sha, Feng,Wu, Xin-Yan

, p. 2063 - 2072 (2015)

A highly enantioselective Michael addition of nitroalkanes to α,β-unsaturated ketones was developed. In the presence of a chiral primary amine-thiourea catalyst based on dehydroabietic amine, γ-nitro ketones were obtained with excellent enantioselectiviti

Optically Active 4-Substituted 5-Nitropentan-2-ones: Valuable Chiral Building Blocks for the Stereocontrolled Construction of Spiro-Pyrazolone Scaffolds with Five Contiguous Stereogenic Centers

Sun, Jiao,Jiang, Cuiping,Zhou, Zhenghong

, p. 1165 - 1172 (2016)

The application of readily available optically active 4-substituted 5-nitropentan-2-ones as chiral building blocks in the stereocontrolled construction of spiro-pyrazolone scaffolds was investigated. In the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (

Asymmetric Conjugate Addition of Nitroalkanes to Enones Using a Sulfonamide-Thiourea Organocatalyst

Kawada, Masahiro,Nakashima, Kosuke,Hirashima, Shin-Ichi,Yoshida, Akihiro,Koseki, Yuji,Miura, Tsuyoshi

, p. 6986 - 6991 (2017)

The asymmetric conjugate addition of nitroalkanes to α,β-unsaturated ketones in the presence of a catalytic amount of a novel sulfonamide-thiourea organocatalyst resulted in the corresponding γ-nitro carbonyl products in high yields with excellent enantio

Helical-Peptide-Catalyzed Enantioselective Michael Addition Reactions and Their Mechanistic Insights

Ueda, Atsushi,Umeno, Tomohiro,Doi, Mitsunobu,Akagawa, Kengo,Kudo, Kazuaki,Tanaka, Masakazu

, p. 6343 - 6356 (2016/08/16)

Helical peptide foldamer catalyzed Michael addition reactions of nitroalkane or dialkyl malonate to α,β-unsaturated ketones are reported along with the mechanistic considerations of the enantio-induction. A wide variety of α,β-unsaturated ketones, including β-aryl, β-alkyl enones, and cyclic enones, were found to be catalyzed by the helical peptide to give Michael adducts with high enantioselectivities (up to 99%). On the basis of X-ray crystallographic analysis and depsipeptide study, the amide protons, N(2)-H and N(3)-H, at the N terminus in the α-helical peptide catalyst were crucial for activating Michael donors, while the N-terminal primary amine activated Michael acceptors through the formation of iminium ion intermediates.

C3-symmetric proline-functionalized organocatalysts: Enantioselective michael addition reactions

Moorthy, Jarugu Narasimha,Saha, Satyajit

experimental part, p. 6359 - 6365 (2011/03/17)

C3-Symmetric, tripodal catalyst 4 based on 1,3,5- triethylbenzene, which incorporates the features of a molecular receptor, is shown to catalyze Michael addition reactions ofcarbonyl compounds to β-nitrostyrenes in a high stereoselectivity (up to 99:1a dr and up to 98%ee). Copyright

Primary amine-thioureas based on tert-butyl esters of natural amino acids as organocatalysts for the Michael reaction

Kokotos, Christoforos G.,Kokotos, George

experimental part, p. 1355 - 1362 (2009/12/09)

A new class of primary amine-thioureas based on tert-butyl esters of (S)-α-amino acids and (1S,2S)-diphenylethylenediamine was synthesized and their activity as catalysts in Michael additions was evaluated. Derivatives based on di-tert-butyl aspartate and

A novel bifunctional sulfonamide primary amine-catalyzed enantioselective conjugate addition of ketones to nitroolefins
