Check Digit Verification of cas no

The CAS Registry Mumber 1577131-71-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,7,1,3 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1577131-71:
(9*1)+(8*5)+(7*7)+(6*7)+(5*1)+(4*3)+(3*1)+(2*7)+(1*1)=175
175 % 10 = 5
So 1577131-71-5 is a valid CAS Registry Number.

, p. 295 - 306 (2014)

A novel compound crystallizes in the triclinic space group P-1 with a = 7.674(4) ?, b = 12.584(6) ?, c = 15.921(6) ?, α = 89.62(4), β = 84.34(4), γ = 73.77(4) and Z = 4. This compound contains Schiff base and rings of molecule has (E) configuration with respect to the central CN double bond. The crystal structure has the intramolecular OHa?N and the intermolecular CHa?O hydrogen bonds. Molecular modeling of the title compound was done by using density functional theories (DFT). Detailed vibrational assignments have been made on the basis of potential energy distribution (PED). Additionally, chemical shift assignments, investigations of thermodynamical parameters and plotting of molecular electrostatic potential surfaces have been performed with the help of DFT method. In order to understand the electronic transitions of the title compound, time dependent DFT (TD-DFT) calculations were performed in gas phase. The dipole moment, linear polarizabilities, anisotropy and first hyperpolarizabilities values have been also computed using the same method.
