2,2'-diphenyl-5,5'-methanediyl-bis-[1,3]dioxane-4,6-dione is a complex organic compound with the molecular formula C20H14O6. It is characterized by a central methanediyl group (-CH2-) connecting two diphenyl rings, with each phenyl ring containing a 1,3-dioxane-4,6-dione moiety. This structure is composed of two ether oxygen atoms (O) and two carbonyl groups (C=O) within the dioxane ring, which is a seven-membered cyclic ether. The compound is known for its rigid structure and is often used in the synthesis of various pharmaceuticals and chemical compounds due to its unique properties. It is also recognized for its potential applications in materials science, particularly in the development of polymers and other advanced materials.

Check Digit Verification of cas no

The CAS Registry Mumber 4721-46-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,2 and 1 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4721-46:
(6*4)+(5*7)+(4*2)+(3*1)+(2*4)+(1*6)=84
84 % 10 = 4
So 4721-46-4 is a valid CAS Registry Number.
