3,3-Bis(4-sodiooxyphenyl)-4,5,6,7-tetraiodo-1(3H)-isobenzofuranone is a complex organic compound with the molecular formula C20H8O4S2I4. It is characterized by the presence of two sodium-oxygenated phenyl groups attached to the 3,3-positions of an isobenzofuranone core, which is further substituted with four iodine atoms at the 4,5,6,7-positions. 3,3-Bis(4-sodiooxyphenyl)-4,5,6,7-tetraiodo-1(3H)-isobenzofuranone is likely to be a synthetic intermediate or a specialty chemical used in advanced chemical research or pharmaceutical applications, given its highly functionalized structure. The presence of multiple iodine atoms suggests potential applications in areas where heavy atom effects or radiopaque properties are beneficial, such as in imaging or as a contrast agent.

Check Digit Verification of cas no

The CAS Registry Mumber 128-72-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128-72:
(5*1)+(4*2)+(3*8)+(2*7)+(1*2)=53
53 % 10 = 3
So 128-72-3 is a valid CAS Registry Number.
