Check Digit Verification of cas no
The CAS Registry Mumber 15192-26-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,1,9 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 15192-26:
(7*1)+(6*5)+(5*1)+(4*9)+(3*2)+(2*2)+(1*6)=94
94 % 10 = 4
So 15192-26-4 is a valid CAS Registry Number.

The standard molar enthalpies of formation of WTe2(cr) and TeF6(g) have been determined by combustion calorimetry in high-pressure fluorine: ΔfHmo(WTe2, cr, 298.15K) = -(38+/-5)kJmol-1, and ΔfHsub
Some investigations of the chemistry of tellurium chloride pentafluoride, its reaction with caesium fluoride, and the preparation of cis and trans methoxytellurium(VI)chloride tetrafluoride, (CH3O)TeClF4
Lawlor, Lawrence J.,Passmore, Jack
, p. 1477 - 1482 (2007/10/02)
The reaction of TeClF5 with CH3OH, and CH3OSiMe3, leads to a mixture of cis- and trans-(CH3O)TeClF4 in a ratio of 1:6, as well as some unidentified Te(IV) product.The vibrational spectrum of the 1:6 mixture of cis- and trans-(CH3O)TeClF4 was accounted for on the basis of the predominant pseudo-C4v trans isomer.TeClF5 is unreactive towards anhydrous HF, SbF5, AlCl3, SO2, F2, and ClF at room temperature.Over the temperature range 70-250 deg C it thermally decomposes to TeF6, TeF4, and Cl2.It slowly reacts with CsF to form CsTeF5, TeF6, Cl2, and small amounts of ClF, and with HNMe2 it is also reduced to form TeF4*HNMe2.
