Check Digit Verification of cas no

The CAS Registry Mumber 174906-30-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,9,0 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 174906-30:
(8*1)+(7*7)+(6*4)+(5*9)+(4*0)+(3*6)+(2*3)+(1*0)=150
150 % 10 = 0
So 174906-30-0 is a valid CAS Registry Number.

A Bioinspired Synthesis of Polyfunctional Indoles

Huang, Zheng,Kwon, Ohhyeon,Huang, Haiyan,Fadli, Aziz,Marat, Xavier,Moreau, Magali,Lumb, Jean-Philip

supporting information, p. 11963 - 11967 (2018/09/11)

Polyfunctional indoles bearing substituents at C5 and C6 are prevalent in natural products, pharmaceuticals, agrochemicals, and materials. Owing to the remoteness of the C5 and C6 positions, indoles of this family can be difficult to prepare, and often require multistep syntheses. Herein, we describe a concise process that converts simple derivatives of tyrosine into 5,6-difunctionalized indoles by direct oxidation of C?H, N?H, and O?H bonds. Our work draws inspiration from the biosynthetic polymerization of tyrosine to make melanin pigments, but makes an important departure to provide well-defined indole heterocycles.

Paragraph 0173-0175; 0177, (2018/05/07)

The invention discloses a cobalt complex, a preparation method thereof, and an application thereof in the selective catalysis of a transfer hydrogenation reaction of a cyano group. The structural formula of the cobalt complex is represented by formula I. The cobalt complex is prepared through a reaction of a cobalt salt and an NNP ligand or a PNP ligand under the protection of an inert atmosphere;and the chemical formula of the cobalt salt is CoX12, wherein X1 represents halogen, a sulfate radical, a perchlorate radical, a hexafluorophosphate radical, a hexafluoroantimonate radical, a tetrafluoroborate radical, a trifluoromethanesulfonate radical or a tetra(pentafluorophenyl)borate radical. The cobalt complex can be used in the selective catalysis of the transfer hydrogenation reaction ofthe cyano group to obtain a primary amine compound, a secondary amine compound and a tertiary amine compound, the primary amine compound, the secondary amine compound and the tertiary amine compoundare important intermediates in a series of subsequent functionalizing reactions, and the cobalt complex has a very high catalysis activity, and has great research values and a great application prospect.

Mild and Selective Cobalt-Catalyzed Chemodivergent Transfer Hydrogenation of Nitriles

Shao, Zhihui,Fu, Shaomin,Wei, Mufeng,Zhou, Shaolin,Liu, Qiang

supporting information, p. 14653 - 14657 (2016/11/23)

Herein, we describe a selective cobalt-catalyzed chemodivergent transfer hydrogenation of nitriles to synthesize primary, secondary, and tertiary amines. The solvent effect plays a key role for the selectivity control. The general applicability of this procedure was highlighted by the synthesis of more than 70 amine products bearing various functional groups in high chemoselectivity. Moreover, this mild system achieved >2000 TONs (turnover numbers) for the transfer hydrogenation of nitriles.

Nickel-catalyzed α-arylation of ketones with phenol derivatives

Takise, Ryosuke,Muto, Kei,Yamaguchi, Junichiro,Itami, Kenichiro

, p. 6791 - 6794 (2014/07/08)

The nickel-catalyzed α-arylation of ketones with readily available phenol derivatives (esters and carbamates) provides access to useful α-arylketones. For this transformation, 3,4-bis(dicyclohexylphosphino) thiophene (dcypt) was identified as a new, enabling, air-stable ligand for this transformation. The intermediate of an assumed C-O oxidative addition was isolated and characterized by X-ray crystal-structure analysis.

'N-stereogenic quaternary ammonium salts' from L-amino acids: Synthesis, separation, and absolute configuration

Wu, Hua-Fang,Lin, Wen-Bin,Xia, Li-Zi,Luo, Ying-Gang,Chen, Xiao-Zhen,Li, Guo-You,Zhang, Guo-Lin,Pan, Xin-Fu

experimental part, p. 677 - 688 (2009/08/08)

Diastereoisomeric linear and cyclic 'N-chiral quaternary ammonium salts' (QASs) were efficiently synthesized from corresponding L-amino acids in high yields. The diastereoisomers of each pair of 'N-chiral QASs' were successfully separated. The absolute configurations of these QASs were determined predominately by X-ray single-crystal analysis. The 1H-NMR data of 'N-chiral QASs' provided characteristic information on the configuration of the N-chiral center. 'N-Chiral QASs' exemplified by [N(R)]-2a and [N(S)]-2a are stable in protic and aprotic solvents within a broad pH and temperature range.

Sodium borohydride: A versatile reagent in the reductive N-monoalkylation of α-amino acids and α-amino methyl esters

Verardo, Giancarlo,Geatti, Paola,Pol, Elena,Giumanini, Angelo G.

, p. 779 - 788 (2007/10/03)

α-Amino acids and α-amino methyl esters are easily converted to their N-monoalkyl derivatives by a reductive condensation reaction using several carbonyl compounds in the presence of sodium borohydride. This reducing agent has shown a wide versatility with minor but essential procedural variations. The reaction allows the α-monodeuterium labeling of the new N-substituent by use of sodium borodeuteride.

Synthesis of (9R,12S)- and (9S,12S)-cycloisodityrosine and their N-methyl derivatives

Boger, Dale L.,Zhou, Jiacheng,Borzilleri, Robert M.,Nukui, Seiji,Castle, Steven L.

, p. 2054 - 2069 (2007/10/03)

Full details of the synthesis of (9R,12S)- and (9S,12S)-cycloisodityrosine and their N-methyl derivatives are detailed based on an intramolecular nucleophilic aromatic substitution reaction for formation of the key biaryl ether with 14-membered ring macrocyclization. Their comparison with prior samples and the documentation of a facile C9 epimerization within the natural 9S series are described.
