Check Digit Verification of cas no
The CAS Registry Mumber 7783-71-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7783-71:
(6*7)+(5*7)+(4*8)+(3*3)+(2*7)+(1*1)=133
133 % 10 = 3
So 7783-71-3 is a valid CAS Registry Number.

(N2H6)3TaF8TaF7HF2and Na7TaF8(TaF7)2: Novel fluoride tantalates with different isolated anionic polyhedra
Goreshnik
, p. 13 - 17 (2017)
The reaction of hydrazinium difluoride and TaF5in 66% hydrofluoric acid water solution resulted in the formation of rather unusual (N2H6)3TaF8TaF7HF2compound. Similar procedure started from a TaF5[sbnd]NaF mixture performed in 35% HF water solution resulted in the formation of a Na7TaF8(TaF7)2compound. Synthesis, crystal structures and Raman spectra of these new compounds are reported in this communication. The main feature of both compounds is the presence of discrete TaF83?and TaF72?anions in their crystal structures, which was also confirmed by Raman spectroscopy.

Chemical interaction of transition metals (Mo, W, Ta, Nb, and Ti) with a tetrafluoroethylene-vinylidene fluoride (TFE-VDF) copolymer (21 mol % TFE + 79 mol % VDF) has been studied by differential scanning calorimetry (DSC) and mass spectrometry. The DSC c
The infrared spectra of products of tantalum and ruthenium reactions with fluorine isolated in solid argon
Osin,Davlyatshin,Ogden
, p. 1312 - 1318 (2007/10/03)
The IR spectra of the products formed when molecular fluorine was passed over tantalum and ruthenium heated to 100-1100°C and isolated in inert matrices at 12 K were studied. In the Ta + F2 system, bands of (TaF5)3, TaF5, and TaF4 were observed. In the Ru + F2 system, the major reaction product was monomeric ruthenium pentafluoride. The structures of metal fluorides of various compositions are discussed.
