Check Digit Verification of cas no

The CAS Registry Mumber 33316-99-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,1 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 33316-99:
(7*3)+(6*3)+(5*3)+(4*1)+(3*6)+(2*9)+(1*9)=103
103 % 10 = 3
So 33316-99-3 is a valid CAS Registry Number.

Synthesis, structure, and fluorescence of isomeric indolizinediones. Carbonyl-bridged isodipyrrinones

Boiadjiev, Stefan E.,Lightner, David A.

, p. 553 - 565 (2007/10/03)

In "one-pot" reactions, pyrrole-α- and β-aldehydes condense readily with 4-ethyl-3-methyl-3-pyrrolin-2-one to give isodipyrrinone analogs, which undergo intramolecular cyclization when the pyrrolealdehyde possesses an α or β-CO2R group. The res
