Δ4,4'-7,7'-dimethoxy-2,2'-diphenyl-4-(benzotelluropyranyl)-4H-benzotelluropyran is a complex organic compound with a molecular formula of C28H22O4Te. It features a benzotelluropyran core, which is a heterocyclic ring system containing a tellurium atom. The molecule is characterized by two phenyl groups (C6H5) connected at the 2,2' positions, and two methoxy groups (-OCH3) attached at the 7,7' positions. The telluropyranyl group is attached to the 4-position of the benzotelluropyran core, which may influence the compound's electronic properties and reactivity. Δ4,4'-7,7'-dimethoxy-2,2'-diphenyl-4-(benzotelluropyranyl)-4H-benzotelluropyran could be of interest in materials science, medicinal chemistry, or as a precursor in the synthesis of other organotellurium compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 80697-43-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,9 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80697-43:
(7*8)+(6*0)+(5*6)+(4*9)+(3*7)+(2*4)+(1*3)=154
154 % 10 = 4
So 80697-43-4 is a valid CAS Registry Number.
