Check Digit Verification of cas no

The CAS Registry Mumber 99447-78-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,4 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99447-78:
(7*9)+(6*9)+(5*4)+(4*4)+(3*7)+(2*7)+(1*8)=196
196 % 10 = 6
So 99447-78-6 is a valid CAS Registry Number.

?-? Molecular Complexes with Nitrones: PartIV - Substituent Effect in the Complexation of Aryl Nitrones with Tetracyanoethylene and 1,4-Benzoquinones

Nour El-Din, Ahmed M.

, p. 511 - 512 (2007/10/02)

Charge-transfer complexes of some substituted nitrones with tetracyanoethylene and 1,4-benzoquinones have been studied spectrophotometrically.The stoichiometry and apparent formation constants of the complexes have been determined.From the energies of the charge-transfer transitions, the ionization potentials of the donors have been obtained.
