153511-19-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 153511-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,5,1 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 153511-19:
(8*1)+(7*5)+(6*3)+(5*5)+(4*1)+(3*1)+(2*1)+(1*9)=104
104 % 10 = 4
So 153511-19-4 is a valid CAS Registry Number.

Conformational Effects of [Ni2(μ-ArS)2] Cores on Their Electrocatalytic Activity

Mondragón-Díaz, Alexander,Robles-Marín, Elvis,Murueta-Cruz, Brenda A.,Aquite, Juan C.,Martínez-Alanis, Paulina R.,Flores-Alamo, Marcos,Aullón, Gabriel,Benítez, Luis Norberto,Castillo, Ivan

Two nickel complexes supported by tridentate NS2 ligands, [Ni2(κ-N,S,S,S′-NPh{CH2(MeC6H2R′)S}2)2] (1; R′=3,5-(CF3)2C6H3) and [Ni2(κ-N,S,S,S′-NiBu{CH2C6H4S}2)2] (2), were prepared as bioinspired models of the active site of [NiFe] hydrogenases. The solid-state structure of 1 reveals that the [Ni2(μ-ArS)2] core is bent, with the planes of the nickel centers at a hinge angle of 81.3(5)°, whereas 2 shows a coplanar arrangement between both nickel(II) ions in the dimeric structure. Complex 1 electrocatalyzes proton reduction from CF3COOH at ?1.93 (overpotential of 1.04 V, with icat/ip≈21.8) and ?1.47 V (overpotential of 580 mV, with icat/ip≈5.9) versus the ferrocene/ferrocenium redox couple. The electrochemical behavior of 1 relative to that of 2 may be related to the bent [Ni2(μ-ArS)2] core, which allows proximity of the two Ni???Ni centers at 2.730(8) ?; thus possibly favoring H+ reduction. In contrast, the planar [Ni2(μ-ArS)2] core of 2 results in a Ni???Ni distance of 3.364(4) ? and is unstable in the presence of acid.
