Check Digit Verification of cas no
The CAS Registry Mumber 15098-87-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,0,9 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 15098-87:
(7*1)+(6*5)+(5*0)+(4*9)+(3*8)+(2*8)+(1*7)=120
120 % 10 = 0
So 15098-87-0 is a valid CAS Registry Number.

19F NMR study of the equilibria and dynamics of the Al3+/F- system
Bodor,Toth,Banyai,Szabo,Hefter
, p. 2530 - 2537 (2008/10/08)
A careful reinvestigation by high-field 19F NMR (470 MHz) spectroscopy has been made of the Al3+/F- system in aqueous solution under carefully controlled conditions of pH, concentration, ionic strength (I), and temperature. The 19F NMR spectra show five distinct signals at 278 K and I = 0.6 M (TMACl) which have been attributed to the complexes AlF(i)((3-i)+)(aq) with i ≤ 5. There was no need to invoke AlF(i)(OH)(j)((3-i-j)+) mixed complexes in the model under our experimental conditions (pH ≤ 6.5), nor was any evidence obtained for the formation of AlF63-(aq) at very high ratios of F-/Al3+. The stepwise equilibrium constants obtained for the complexes by integration of the 19F signals are in good agreement with literature data given the differences in medium and temperature. In I = 0.6 M TMACl at 278 K and in I = 3 M KCl at 298 K the log K(i) values are 6.42, 5.41, 3.99, 2.50, and 0.84 (for species i = 1 - 5) and 6.35, 5.25, and 4.11 (for species i = 1 - 3), respectively. Disappearance of the 19F NMR signals under certain conditions was shown to be due to precipitation. Certain 19F NMR signals exhibit temperature- and concentration-dependent exchange broadening. Detailed line shape analysis of the spectra and magnetization transfer measurements indicate that the kinetics are dominated by F- exchange rather than complex formation. The detected reactions and their rate constants are AlF22+ + *F- ? AlF*F2+ + F- (k02 = (1.8 ± 0.3) x 106 M-1 s-1), AlF30 + *F- ? AlF2*F0 + F- (k03 = (3.9 ± 0.9) x 106 M-1 s-1), and AlF30 + H*F ? AlF2*F0 + HF (k(H)03 = (6.6 ± 0.5) x 104 M-1 s-1). The rates of these exchange reactions increase markedly with increasing F- substitution. Thus, the reactions of AlF2+(aq) were too inert to be detected even on the T1 NMR time scale, while some of the reactions of AlF30(aq) were fast, causing large line broadening. The ligand exchange appears to follow an associative interchange mechanism. The cis-trans isomerization of AlF2+(aq), consistent with octahedral geometry for that complex, is slowed sufficiently to be observed at temperatures around 270 K. Difference between the Al3+/F- system and the much studied Al3+/OH- system are briefly commented on.
