756795-28-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 756795-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,6,7,9 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 756795-28:
(8*7)+(7*5)+(6*6)+(5*7)+(4*9)+(3*5)+(2*2)+(1*8)=225
225 % 10 = 5
So 756795-28-5 is a valid CAS Registry Number.

Investigations of Solid State Reactions of Binary Polyphosphate-Fluoride Systems by Means of Thermal Analysis, X-Ray Diffraction and NMR Spectroscopy. - IV. Systems M(PO3)3 + MF3 (M = Al, La)

Ehrt, D.,Jaeger, C.

, p. 97 - 108 (2007/10/02)

The reactions of Al(PO3)3 with AlF3 and of La(PO3)3 with LaF3 can mainly be described by the formula: .As function of the temperature the tridymite-like modification of AlPO4 (? = 30.7 ppm), the cristobalite-like form (? = 27.8 ppm) and berlinite (? = 25.4 ppm) are found both by NMR and X-ray investigations.The 31P chemical shift parameters of LaPO4 are: ? = (5.7 +/- 0.5)ppm, Δ? = (15 +/- 5) ppm and η ca. 1. - Keywords: NMR (MAS) in solids / Solid state reactions / Phosphate-fluoride systems
