Check Digit Verification of cas no

The CAS Registry Mumber 4974-85-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,7 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4974-85:
(6*4)+(5*9)+(4*7)+(3*4)+(2*8)+(1*5)=130
130 % 10 = 0
So 4974-85-0 is a valid CAS Registry Number.

Selective Carbon-Carbon Bond Amination with Redox-Active Aminating Reagents: A Direct Approach to Anilines?

Qiu, Xu,Wang, Yachong,Su, Lingyu,Jin, Rui,Song, Song,Qin, Qixue,Li, Junhua,Zong, Baoning,Jiao, Ning

supporting information, p. 3011 - 3016 (2021/09/13)

Amines are among the most fundamental motifs in chemical synthesis, and the introduction of amine building blocks via selective C—C bond cleavage allows the construction of nitrogen compounds from simple hydrocarbons through direct skeleton modification. Herein, we report a novel method for the preparation of anilines from alkylarenes via Schmidt-type rearrangement using redox-active amination reagents, which are easily prepared from hydroxylamine. Primary amines and secondary amines were prepared from corresponding alkylarenes or benzyl alcohols under mild conditions. Good compatibility and valuable applications of the transformation were also displayed.

Aminotriazole Mn(I) Complexes as Effective Catalysts for Transfer Hydrogenation of Ketones

Martínez-Ferraté, Oriol,Werlé, Christophe,Franciò, Giancarlo,Leitner, Walter

, p. 4514 - 4518 (2018/10/20)

A catalytic system based on complexes comprising abundant and cheap manganese together with readily available aminotriazole ligands is reported. The new Mn(I) complexes are catalytically competent in transfer hydrogenation of ketones with 2-propanol as hydrogen source. The reaction proceeds under mild conditions at 80 °C for 20 h with 3 % of catalyst loading using either KOtBu or NaOH as base. Good to excellent yields were obtained for a wide substrate scope with broad functional group tolerance. The obtained results by varying the substitution pattern of the ligand are consistent with an out-sphere mechanism for the H-transfer.

Ruthenium-catalyzed remote electronic activation of aromatic C-F bonds

Watson, Andrew J. A.,Atkinson, Benjamin N.,Maxwell, Aoife C.,Williams, Jonathan M. J.

, p. 734 - 740 (2013/04/10)

The tandem isomerization and nucleophilic aromatic substitution of allylic fluoro-substituted benzylic alcohols is described for the first time. In the presence of the ruthenium complex Ru(PPh3)3(CO)(H) 2, 1-(4-fluorophenyl)prop-2-en-1-ol is converted into the corresponding para-amino ketone or para-phenolic substituted ketone. Copyright
