Incompatibilities
A weak base. Reacts with strong oxidizers, bromine azide, acids and decomposes on contact with strong acids producing acetic acid fumes. Arsine, a very deadly gas, can be released in the presence of acid, acid mists, or hydrogen gas.
Check Digit Verification of cas no
The CAS Registry Mumber 7784-41-0 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 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7784-41:
(6*7)+(5*7)+(4*8)+(3*4)+(2*4)+(1*1)=130
130 % 10 = 0
So 7784-41-0 is a valid CAS Registry Number.

Vibrational study by inelastic neutron scattering, infrared absorption and Raman scattering of potassium, rubidium and cesium dihydrogenarsenate crystals: Comparison with thallium dihydrogenarsenate
Le Calve, Nicole,Pasquier, Bernadette,Ouafik, Zahra
, p. 299 - 313 (1997)
The vibrational study of polycrystalline potassium, rubidium and cesium dihydrogenarsenates, KH2AsO4, RbH2AsO4 and CsH2AsO4, has been undertaken in the 20-4000 cm-1 range. The inelastic neutron scattering spectra obtained at 20 K allow a precise assignment of the OH vibrations. The infrared absorption and Raman scattering spectra of the paraelectric and ferroelectric phases have been analyzed. The three compounds are isomorphous with KH2PO4. The results are compared to those obtained for the thallium dihydrogenarsenate T1H2AsO4. In all compounds the proton dynamics appear weakly coupled to heavy atoms motions. The order-disorder transition at Tc is associated to relaxational motions of anions and protons in the tetragonal potassium, rubidium and cesium dihydrogenarsenates and to collective reorientational motions of anions in monoclinic thallium derivative. The spectroscopic features show the participation of cations K+, Rb+ and Cs+ to the dynamics of the three-dimensional lattice in both phases. In contrast, heavy-cation T1+ motions are decoupled from the dynamics of hydrogen bond layers. No correlation between ordering of lattice and OH stretching wavenumber is observed.
