Check Digit Verification of cas no
The CAS Registry Mumber 7722-76-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,2 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7722-76:
(6*7)+(5*7)+(4*2)+(3*2)+(2*7)+(1*6)=111
111 % 10 = 1
So 7722-76-1 is a valid CAS Registry Number.

Solid-Phase Interaction of Fluorapatite with Ammonium Hydrogen Difluoride
Laptash, N. M.,Kaidalova, T. A.
, p. 535 - 537 (2008/10/08)
A solid-phase interaction of fluorapatite with ammonium difluoride was studied in the temperature range 25-900°C. At room temperature, calcium fluoride and ammonium dihydrogen phosphate or isostructural ammonium florophosphate were formed as the result of grinding a mixture of theinitial components. Above 200°C, the reaction was accompanied by the formation of a volatile phosphor compound. At the final stage of th e process (above 500°C), glassy ammonium hydrogen ultrafluorophosphate of nonstoichiometric composition was formed, which again yielded fluorapatite upon reaction with calcium fluoride.

A study was made of the influence of pH on formation of insoluble compounds in solid APP (Ammonium Polyphosphate). Orthophosphoric acid made by the wet process (WOPA) from Karatau phosphorites of the composition (mass %): P//2O//5//t//o//t equals 23. 1, R//2O//3 equals 2. 9, Fe//2O//3 equals 0. 96, F equals 0. 79, SO//3 equals 2. 5, MgO equals 1. 8 was used in the experiments. It is shown that the production of APP by evaporation and dehydration of ammonium phosphate slurries of various pH values is accompanied by retrogradation of the available and water-soluble form of P//2O//5, which intensifies with increase of pH. This investigation led to the development of a process for production of solid APP from unevaporated orthophosphoric acid obtained from Karatau phosphorites, with insignificant retrogradation of available P//2O//5.
