637-03-6 Usage
Chemical Properties
WHITE TO ALMOST WHITE CRYSTALS OR CRYST. POWDER
Uses
Phenylarsine oxide is used as a poultry coccidiostat in veterinary medicine. It is also used in a membrane-permeable protein tyrosine phosphatase inhibitor.
Definition
ChEBI: An arsine oxide derived from phenylarsine.
General Description
Phenylarsine oxide (PhAsO4) is a bifunctional SH group chemical. It is hydrophobic in nature.
Biochem/physiol Actions
Phenylarsine oxide?(PAO) can reduce the motility and sustainability of Setaria cervi. It has the ability to stimulate cyclosporin A-sensitive transition in the presence of EGTA (ethylene glycol-bis(β-aminoethyl ether)-N,N,N′,N′-tetraacetic acid). It acts as a stimulator of mitochondrial ion fluxes.
Safety Profile
Poison by intravenous and intraperitoneal routes. When heated to decomposition it emits toxic fumes of As. See also ARSENIC COMPOUNDS
Check Digit Verification of cas no
The CAS Registry Mumber 637-03-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 637-03:
(5*6)+(4*3)+(3*7)+(2*0)+(1*3)=66
66 % 10 = 6
So 637-03-6 is a valid CAS Registry Number.
