"6'.7'-Dimethoxy-1'.4'.9'.10'-tetrahydrospiro<1.3-dioxolan-2'.3'(2'H)-phenanthren>" is a complex organic compound characterized by its unique molecular structure. It features a spiro arrangement, which means it has two rings sharing a common atom. In this case, the spiro system connects a 1,3-dioxolan ring with a phenanthren ring. The phenanthren ring is a polycyclic aromatic hydrocarbon with four fused rings, and the 1,3-dioxolan ring is a five-membered ring with two oxygen atoms. The compound is further defined by the presence of methoxy groups at the 6' and 7' positions, which are -OCH3 groups attached to the phenanthren ring. The "1'.4'.9'.10'-tetrahydro" part of the name indicates that the compound has four hydrogen atoms added to the phenanthren ring, making it a tetrahydro derivative. 6'.7'-Dimethoxy-1'.4'.9'.10'-tetrahydrospiro<1.3-dioxolan-2'.3'(2'H)-phenanthren> is likely to be found in the field of organic chemistry, potentially as a synthetic intermediate or a compound with specific pharmacological properties, given the presence of oxygenated functional groups and the polycyclic nature of the molecule.
The CAS Registry Mumber 5869-10-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,6 and 9 respectively; the second part has 2 digits, 1 and 0 respectively. Calculate Digit Verification of CAS Registry Number 5869-10: (6*5)+(5*8)+(4*6)+(3*9)+(2*1)+(1*0)=123 123 % 10 = 3 So 5869-10-3 is a valid CAS Registry Number.
