3-((Ξ)-2,4-dinitro-benzylidene)-dihydro-furan-2-one is a complex organic chemical compound characterized by a dihydrofuran-2-one core structure, which features a five-membered ring with one oxygen atom and a ketone group. The compound is further defined by a 2,4-dinitro-benzylidene moiety, which is a benzene ring with nitro groups at the 2nd and 4th positions, connected to the dihydrofuran-2-one through a double bond (denoted by Ξ, indicating the Z configuration). This specific arrangement of functional groups endows the molecule with unique chemical properties, making it a potential candidate for various applications in the fields of chemistry and materials science.
The CAS Registry Mumber 1530-67-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,3 and 0 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 1530-67: (6*1)+(5*5)+(4*3)+(3*0)+(2*6)+(1*7)=62 62 % 10 = 2 So 1530-67-2 is a valid CAS Registry Number.
