It is a colorless, volatile liquid that is soluble in water and has a sweet, ether-like odor. Diethoxycarbonate is primarily used as a solvent, a reagent in organic synthesis, and as a component in the production of pharmaceuticals, pesticides, and other chemicals. It is also used as a gasoline additive to improve octane ratings and as a component in the production of polyurethane foams. Due to its potential health and environmental risks, proper handling and disposal procedures are essential when working with diethoxycarbonate.
The CAS Registry Mumber 4091-69-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,9 and 1 respectively; the second part has 2 digits, 6 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4091-69: (6*4)+(5*0)+(4*9)+(3*1)+(2*6)+(1*9)=84 84 % 10 = 4 So 4091-69-4 is a valid CAS Registry Number.
