Check Digit Verification of cas no

The CAS Registry Mumber 1262055-68-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,0,5 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1262055-68:
(9*1)+(8*2)+(7*6)+(6*2)+(5*0)+(4*5)+(3*5)+(2*6)+(1*8)=134
134 % 10 = 4
So 1262055-68-4 is a valid CAS Registry Number.

An Effective [FeIII(TF4DMAP)Cl] Catalyst for C-H Bond Amination with Aryl and Alkyl Azides

Du, Yi-Dan,Xu, Zhen-Jiang,Zhou, Cong-Ying,Che, Chi-Ming

, p. 895 - 899 (2019)

[FeIII(TF4DMAP)Cl] can efficiently catalyze intermolecular sp3 C-H amination using aryl azides and intramolecular sp3 C-H amination of alkyl azides in moderate-to-high product yields. At catalyst loading down to 1 mol %, the reactions display high chemo- and regioselectivity with broad substrate scope and are effective for late-stage functionalization of complex natural/bioactive molecules.

Synthesis and catalytic activity of μ-oxo ruthenium(IV) porphyrin species to promote amination reactions

Zardi, Paolo,Intrieri, Daniela,Carminati, Daniela Maria,Ferretti, Francesco,MacChi, Piero,Gallo, Emma

, p. 1156 - 1165 (2016/12/16)

This work describes the synthesis of ruthenium(IV) m-oxo porphyrin complexes of general formula [RuIV(TPP)(X)]2O which have been applied as catalysts in nitrene transfer reactions using aryl azides (ArN3) as nitrene sources. Collected data indicated that the catalytic efficiency of [RuIV(TPP)(OCH3)]2O was comparable to that of RuII(TPP)CO because of their analogous reactivity towards aryl azides to give the same catalytically active bis-imido species RuVI(TPP)(ArN)2. The reaction of [RuIV(TPP)(OCH3)]2O with Ph3CN3 or (CH3)3SiN3 afforded [RuIV(TPP)(N3)]2O which was fully characterised, its molecular structure was also determined by single crystal X-ray analysis.

Ruthenium porphyrins-catalyzed atom-efficient amination of C-H bonds by arylazides

Intrieri, Daniela,Caselli, Alessandro,Ragaini, Fabio,Cenini, Sergio,Gallo, Emma

experimental part, p. 732 - 740 (2011/11/14)

Benzylic amines are synthesized in yield up to 90% by the Ru(TPP)CO-catalyzed amination of both exocyclic and endocyclic benzylic C-H bonds. The choice of arylazides as nitrogen sources confers to the methodology a good sustainability due to the formation of molecular nitrogen as the only stoichiometric by-product. A preliminary mechanistic investigation evidenced a critical role of the hydrocarbon concentration to drive the chemoselectivity of the reaction.
