Check Digit Verification of cas no

The CAS Registry Mumber 12788-24-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,7,8 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 12788-24:
(7*1)+(6*2)+(5*7)+(4*8)+(3*8)+(2*2)+(1*4)=118
118 % 10 = 8
So 12788-24-8 is a valid CAS Registry Number.

Heat capacity of some liquid Zintl compounds: Equiatomic alkali-lead alloys

Saboungi, Marie-Louise,Reijers, H. T. J.,Blander, M.,Johnson, G. K.

, p. 5869 - 5875 (1988)

Enthalpies for equiatomic APb (A = Na, Rb, and Cs) have been measured by high- temperature drop calorimetry over a temperature range covering solid and liquid phases.Thermodynamic information on the solid state transitions and the melting process is derived.With the exception of NaPb, the heat capacities of the liquid alloys show a remarkably strong negative temperature dependence above the melting point.It is suggested that this behavior is a consequence of the dissociation of molecular entities present in the liquid state related to the Zintl structures detected in the corresponding solid compounds.Thermodynamic calculations based on the presence of polyvalently charged anions yield valuable information on the temperature dependence of the concentration of these species.
