Check Digit Verification of cas no

The CAS Registry Mumber 77541-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,4 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77541-40:
(7*7)+(6*7)+(5*5)+(4*4)+(3*1)+(2*4)+(1*0)=143
143 % 10 = 3
So 77541-40-3 is a valid CAS Registry Number.

CORRELATION OF KINETIC DATA OF 1,3-DIPOLAR CYCLOADDITIONS OF C-BENZOYL-N-PHENYLNITRONES WITH THE HOMO ENERGIES OF FURAN DERIVATIVES

Fisera, Lubor,Gaplovsky, Anton,Timpe, Hans-Joachim,Kovac, Jaroslav

, p. 1504 - 1512 (2007/10/02)

Application of PMO treatment to 1,3-dipolar cycloaddition of C-benzoyl-N-phenylnitrone with furan derivatives is described.Ionisation potentials of 2-R-substituted furan derivatives (R=H, CH3, C2H5, CH2OH, CH2OCOCH3, C6H5, CHO) and 2,5-dimethylfurane representing experimental values of the HOMO energies have been determined from energies of the respective charge-transfer complexes with TCNE.Good correlation between IP and k2 rate constants indicates that the reaction is controlled by the LUMO(nitrone)/HOMO(furan deriv.) interaction.Electron affinities of the furanderivatives were determined from IP and energies of ?-?*transitions using empirical equation ΔE(?-?*)=IP-EA-450.58 kJ mol-1.
