Check Digit Verification of cas no

The CAS Registry Mumber 227078-96-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,0,7 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 227078-96:
(8*2)+(7*2)+(6*7)+(5*0)+(4*7)+(3*8)+(2*9)+(1*6)=148
148 % 10 = 8
So 227078-96-8 is a valid CAS Registry Number.

Interrogation of 2,2′-Bipyrimidines as Low-Potential Two-Electron Electrolytes

Griffin, Jeremy D.,Pancoast, Adam R.,Sigman, Matthew S.

As utilization of renewable energy sources continues to expand, the need for new grid energy storage technologies such as redox flow batteries (RFBs) will be vital. Ultimately, the energy density of a RFB will be dependent on the redox potentials of the respective electrolytes, their solubility, and the number of electrons stored per molecule. With prior literature reports demonstrating the propensity of nitrogen-containing heterocycles to undergo multielectron reduction at low potentials, we focused on the development of a novel electrolyte scaffold based upon a 2,2′-bipyrimidine skeleton. This scaffold is capable of storing two electrons per molecule while also exhibiting a low (~-2.0 V vs Fc/Fc+) reduction potential. A library of 24 potential bipyrimidine anolytes were synthesized and systematically evaluated to unveil structure-function relationships through computational evaluation. Through analysis of these relationships, it was unveiled that steric interactions disrupting the planarity of the system in the reduced state could be responsible for higher levels of degradation in certain anolytes. The major decomposition pathway was ultimately determined to be protonation of the dianion by solvent, which could be reversed by electrochemical or chemical oxidation. To validate the hypothesis of strain-induced decomposition, two new electrolytes with minimal steric encumbrance were synthesized, evaluated, and found to indeed exhibit higher stability than their sterically hindered counterparts.

Concentrated solar radiation as a renewable heat source for a preparative-scale and solvent-free Biginelli reaction
