Ethyl-diphenyl-isopropyl-phosphonium, also known as EDIPP, is a phosphonium-based ionic liquid with the chemical formula C19H24P. It is a colorless, viscous liquid at room temperature and is widely used in various applications due to its unique properties, such as high thermal stability, low melting point, and non-flammability. EDIPP is often employed as a solvent, catalyst, or electrolyte in chemical reactions, electrochemical processes, and energy storage systems. Its structure consists of an ethyl group, two phenyl rings, and an isopropyl group attached to a central phosphonium cation, with a counterion typically being a halide or other anion. The combination of these functional groups endows EDIPP with its distinctive properties, making it a valuable compound in the field of chemistry and materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 7333-77-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,3 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7333-77:
(6*7)+(5*3)+(4*3)+(3*3)+(2*7)+(1*7)=99
99 % 10 = 9
So 7333-77-9 is a valid CAS Registry Number.
