Check Digit Verification of cas no

The CAS Registry Mumber 13728-58-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,2 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13728-58:
(7*1)+(6*3)+(5*7)+(4*2)+(3*8)+(2*5)+(1*8)=110
110 % 10 = 0
So 13728-58-0 is a valid CAS Registry Number.

Synthesis of a Series of Novel Polycyclic Aromatic Systems: Isomers of Benzanthracene Containing a Cyclopenta-Fused Ring

Sangaiah, R.,Gold, A.,Toney, G. E.

, p. 1632 - 1638 (2007/10/02)

The four possible isomers of benzanthracene containing a cyclopenta-fused ring have been synthesized and characterized.These systems are of interest for structure-activity studies in bioactivation because of their predicted high level of activity.Formation of fused five-membered rings by intramolecular cyclodehydration, often difficult to accomplish, was found to be smoothly effected in anhydrous HF, provided the reactivity index (Nt) for the appropriate electrophilic addition was favorable.The dihydro polycyclic aromatic alcohols obtained from reduction of the c orresponding keto cyclodehydration products were best dehydrated to the desired PAH by activity grade I neutral alumina in refluxing benzene.This dehydration proceeds in high yield without the formation of isomeric or polymeric side products that occurred even under such mild acid catalysis as p-toluenesulfonic acid.
