Check Digit Verification of cas no

The CAS Registry Mumber 107348-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,3,4 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 107348-28:
(8*1)+(7*0)+(6*7)+(5*3)+(4*4)+(3*8)+(2*2)+(1*8)=117
117 % 10 = 7
So 107348-28-7 is a valid CAS Registry Number.

MOLECULAR COMPLEXES OF CYCLOPHANES. XII. ON THE TRANSANNULAR ELECTRONIC INTERACTIONS IN PARACYCLOPHANES

Mourad, Aboul-Fetouh E.,Nour-El-Din, Ahmed M.,Abdel-Nabi, Husham A.

, p. 381 - 384 (2007/10/02)

The interaction of twelve paracyclophane bisazomethynes with 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) in dichloromethane is described in terms of formation of 1:1 charge-transfer (CT) complexes.Association constants and transition energies of these CT complexes as well as ionization potentials of the donors 1-3 have been determined.On the basis of association constants and wavelengths of maximum absorption, the basicity of the donor 1-3 follow the order; pseudo-gem (1) > pseudo-meta (2) > pseudo-para (3), which could be rationalized in terms of the existence of transannular electronic interactions in this donor system.
