Check Digit Verification of cas no

The CAS Registry Mumber 706819-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,0,6,8,1 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 706819-98:
(8*7)+(7*0)+(6*6)+(5*8)+(4*1)+(3*9)+(2*9)+(1*8)=189
189 % 10 = 9
So 706819-98-9 is a valid CAS Registry Number.

Carbon dioxide cleavage by a Ni2 complex supported by a binucleating bis(N-heterocyclic carbene) framework Dedicated to Prof. John E. Bercaw on the occasion of his 70th birthday.

Tsui, Emily Y.,Agapie, Theodor

, p. 103 - 110 (2014)

A binucleating bis(N-heterocyclic carbene) ligand was designed as a means to coordinate and proximally constrain two transition metal centers. Using an imidazopyridine-based NHC afforded a framework structurally related to previously reported para-terphenyl diphosphines. Bimetallic copper, cobalt, and nickel complexes supported by this framework were synthesized and structurally characterized. Strong interactions between the metal centers and the central arene were observed in all nickel complexes. Dinickel(0) complexes of this ligand framework were found to react with CO2 to form a dicarbonyl-bridged dinickel(0) product, demonstrating facile CO2 reduction.

Non-symmetrical, potentially redox non-innocent imino NHC pyridine 'pincers': Via a zinc ion template-assisted synthesis

Simler, Thomas,Danopoulos, Andreas A.,Braunstein, Pierre

, p. 5955 - 5964 (2017/07/10)

New non-symmetrical, redox-active imino NHC pyridine pincer ligands, 2-(R1-imidazol-2-ylidene)-6-(R2NCH)-pyridine (R1 = 2,6-diisopropylphenyl (DiPP), R2 = 2,4,6-trimethylphenyl (Mes), 4B; R1 = R2 = DiPP, 4C), have been accessed by a ZnII-promoted modular synthesis involving the quaternization of R1-imidazole by [Zn(κNimineκNpyridine)(2-(R2NCH)-6-bromo-pyridine)Cl2], followed by ZnII removal and deprotonation of imidazolium pro-ligands. Redox active forms of 4B were implicated in the two complexes obtained by its reaction with FeBr2/KC8; metrical data analysis pointed to the occurrence of radical anionic and dianionic redox states of 4B.

Metal-to-ligand alkyl migration inducing carbon-sulfur bond cleavage in dialkyl yttrium complexes supported by thiazole-containing amidopyridinate ligands: Synthesis, characterization, and catalytic activity in the intramolecular hydroamination reaction

Lyubov, Dmitry M.,Luconi, Lapo,Rossin, Andrea,Tuci, Giulia,Cherkasov, Anton V.,Fukin, Georgy K.,Giambastiani, Giuliano,Trifonov, Alexander A.

, p. 3487 - 3499 (2014/04/03)

Neutral YIII dialkyl complexes supported by tridentate N -,N,N monoanionic methylthiazole- or benzothiazole-amidopyridinate ligands have been prepared and completely characterized. Studies on their stability in solution revealed prog
