Check Digit Verification of cas no
The CAS Registry Mumber 42566-65-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,6 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42566-65:
(7*4)+(6*2)+(5*5)+(4*6)+(3*6)+(2*6)+(1*5)=124
124 % 10 = 4
So 42566-65-4 is a valid CAS Registry Number.

The thermal stability of the salts of metals of the first group with perfluorinated carboxylic acids was investigated by a differential thermal method.The calculations of the A, E, and n parameters were made on a Minsk 32 computer.For the investigated series of salts the reactions has first-order kinetics.In the case of the pyrolysis of the salts of perfluoromethoxypropionic acid the yield of perfluoromethyl vinyl ether depends not only on the cation of the salt but is determined to a significant degree by the structural features of the carbon skeleton.Tetrafluoroethylene and perfluoromethoxypropionyl fluoride were detected as side products.A mechanism for the process, which explains the formation of the main reaction products, was proposed and confirmed experimentally.
