Check Digit Verification of cas no

The CAS Registry Mumber 67699-73-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,9 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67699-73:
(7*6)+(6*7)+(5*6)+(4*9)+(3*9)+(2*7)+(1*3)=194
194 % 10 = 4
So 67699-73-4 is a valid CAS Registry Number.

A NON-ISOTHERMAL KINETIC STUDY OF THE THERMAL DECOMPOSITION OF MAGNESIUM ALKOXIDES AND AMIDES

Ashby, E. C.,Willard, G. Fred

, p. 241 - 246 (2007/10/02)

The thermal decomposition of alkoxides and amides of magnesium have been studied by vacuum TGA under both isothermal and non-isothermal conditions.These compounds were found to follow a unimolecular decay law, which in integrated form is -ln(1-α)=kt, where α is the fraction of material reacted, and k is the Arrhenius rate constant.The rate-controlling process is random nucleation, one nucleus on each particle.Energies of activation calculated by isothermal and non-isothermal methods agree to within +/-20percent.
