Check Digit Verification of cas no
The CAS Registry Mumber 13450-92-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,5 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13450-92:
(7*1)+(6*3)+(5*4)+(4*5)+(3*0)+(2*9)+(1*2)=85
85 % 10 = 5
So 13450-92-5 is a valid CAS Registry Number.

The temperature dependence of the heat capacity of germanium dibromide was studied over the temperature range 8.3-314 K by adiabatic calorimetry. The enthalpy of formation of solid germanium dibromide was determined by solution calorimetry. Scanning calorimetry was used to obtain the thermodynamic characteristics of fusion of GeBr2. The thermodynamic characteristics of the Ge-Br system studied by us earlier were used to consistently calculate the consistent standard enthalpies of formation and absolute entropies of germanium bromides in the solid, liquid, and gaseous states.
