Purification Methods
It is purified by heating at 450o in a stream of Cl2 for 2hours. Some sublimation occurs because the PtCl2 sublimes completely at 560o as red (almost black) needles. This sublimate can be combined to the bulk chloride, and while still at ca 450o it should be transferred to a container and cooled in a desiccator. A probable impurity is PtCl4. To test for this add a few drops of H2O (in which PtCl4 is soluble) to the salt, filter and add an equal volume of saturated aqueous NH4Cl to the filtrate. If no precipitate is formed within 1minute, then the product is pure. If a precipitate appears, then the whole material should be washed with small volumes of H2O until the soluble PtCl4 is removed. The purified PtCl2 is partly dried by suction and then dried in a vacuum desiccator over P2O5. It is insoluble in H2O but soluble in HCl to form chloroplatinic acid (H2PtCl4) by disproportionation.

Check Digit Verification of cas no
The CAS Registry Mumber 10025-65-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,2 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10025-65:
(7*1)+(6*0)+(5*0)+(4*2)+(3*5)+(2*6)+(1*5)=47
47 % 10 = 7
So 10025-65-7 is a valid CAS Registry Number.

, p. 193 - 195 (1984)
A methyl(ethylene)platinum(II) complex has been prepared and characterized; it forms complexes where L = pyridine, Me2S, or C2H4, undergoes exchange with unsaturated reagents (un) where (un) = PhCH=CHPh, CH(CO2Me)=CH(CO2Me), or PhCCPh to give , undergoes insertion with CF3CCCF3 to give, after treatment with pyridine, (py)2>, and reacts with Zeise's dimer to give the unsymmetrical dimer .

, p. 59 - 64 (2008)
Using a static method three individual compounds in system of Pt-Cl: PtCl4, PtCl3, and PtCl2 are shown to exist. PtCl was shown not to exist. The enthalpies of formation of platinum chlorides were measured by calorimetry by reduction of the compounds with gaseous hydrogen. The recommended values for the enthalpies of formation at 298.15 K are -137.7 ± 0.3, 194.2 ± 1.0, and 245.6 ± 1.9 kJ/mol for PtCl2(s), PtCl3(s) and PtCl4(s), respectively.
