It is a yellow to orange solid that is insoluble in water but soluble in organic solvents. 2,4-bis(4-methoxyphenyl)-4-oxobutanenitrile is widely used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds. It is also used in the research and development of new drugs and in the production of specialty chemicals. Additionally, it is known for its versatile reactivity and is commonly used in organic synthesis for the construction of complex molecular structures. However, it should be handled with care as it may cause irritation to the skin, eyes, and respiratory tract, and may be harmful if ingested or inhaled.
Check Digit Verification of cas no
The CAS Registry Mumber 23073-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,0,7 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 23073-04:
(7*2)+(6*3)+(5*0)+(4*7)+(3*3)+(2*0)+(1*4)=73
73 % 10 = 3
So 23073-04-3 is a valid CAS Registry Number.

A convenient preparative method is developed allowing for expeditious assembly of 3,5-diarylsubstituted 5-hydroxy-1,5-dihydro-2H-pyrrol-2-ones from routinely available inexpensive synthetic precursors. These compounds could not be prepared via the previously known protocols, as 2-aminofuran derivatives were produced instead.
