Propane, 1-diazo-3-methoxy-, also known as 1-diazo-3-methoxypropane or DMP, is a colorless, flammable, and toxic liquid with the chemical formula C4H10N2O. It is an important reagent in organic synthesis, particularly in the Wolff rearrangement, a reaction that converts diazo compounds to carbenes. DMP is used as a source of the highly reactive diazomethane, which is a valuable intermediate in the synthesis of various organic compounds. Due to its hazardous nature, DMP is typically handled with caution and stored under specific conditions to prevent decomposition and potential health risks.
The CAS Registry Mumber 821-45-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 1 respectively; the second part has 2 digits, 4 and 5 respectively. Calculate Digit Verification of CAS Registry Number 821-45: (5*8)+(4*2)+(3*1)+(2*4)+(1*5)=64 64 % 10 = 4 So 821-45-4 is a valid CAS Registry Number.
