Benzo[h]naphtho[1,2-c]cinnoline is a heterocyclic aromatic compound characterized by a unique fusion of benzene, naphthalene, and cinnoline rings. This complex structure is formed by the condensation of benzene with naphthalene and cinnoline, resulting in a tricyclic system with a nitrogen atom in the cinnoline ring. The compound exhibits interesting chemical properties due to its conjugated π-electron system and the presence of nitrogen, which can participate in various chemical reactions, such as electrophilic aromatic substitution and nucleophilic addition. Benzo[h]naphtho[1,2-c]cinnoline has potential applications in the synthesis of pharmaceuticals, dyes, and other organic compounds due to its diverse reactivity and structural features.
The CAS Registry Mumber 213-51-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,1 and 3 respectively; the second part has 2 digits, 5 and 1 respectively. Calculate Digit Verification of CAS Registry Number 213-51: (5*2)+(4*1)+(3*3)+(2*5)+(1*1)=34 34 % 10 = 4 So 213-51-4 is a valid CAS Registry Number.
