2,7-diphenyl-1,8-dihydro-pyrimido[4,5,6-gh]perimidine is a complex organic compound belonging to the class of perimidine derivatives. It features a pyrimido[4,5,6-gh]perimidine core structure, which is a fused polycyclic aromatic system. The molecule is characterized by two phenyl groups attached at the 2 and 7 positions, and a 1,8-dihydro functional group, indicating the presence of two hydrogen atoms bonded to carbon atoms at these positions, which introduces a degree of saturation to the molecule. 2,7-diphenyl-1,8-dihydro-pyrimido[4,5,6-gh]perimidine is of interest in the field of organic chemistry, potentially for its unique electronic properties and structural characteristics, which could have implications in materials science or as a building block in the synthesis of more complex molecules.
The CAS Registry Mumber 4647-91-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 7 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 4647-91: (6*4)+(5*6)+(4*4)+(3*7)+(2*9)+(1*1)=110 110 % 10 = 0 So 4647-91-0 is a valid CAS Registry Number.
