1-Ethyl-1-methyl-4-phenyl-piperidinium iodide, also known as EMPP, is a quaternary ammonium salt with the chemical formula C18H26IN. It is a white crystalline solid that is soluble in water and organic solvents. EMPP is used as a phase-transfer catalyst in various chemical reactions, particularly in the synthesis of pharmaceuticals and agrochemicals. It facilitates the transfer of reactants between immiscible phases, such as between an aqueous and an organic phase, thereby enhancing the reaction rate and selectivity. Due to its ability to improve the efficiency of chemical processes, EMPP has become an important tool in the field of organic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 884-00-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,8 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 884-00:
(5*8)+(4*8)+(3*4)+(2*0)+(1*0)=84
84 % 10 = 4
So 884-00-4 is a valid CAS Registry Number.
