Check Digit Verification of cas no

The CAS Registry Mumber 76890-10-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,8,9 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76890-10:
(7*7)+(6*6)+(5*8)+(4*9)+(3*0)+(2*1)+(1*0)=163
163 % 10 = 3
So 76890-10-3 is a valid CAS Registry Number.

SYNTHESIS OF METHYL-SUBSTITUTED INDENOQUINOLINES, INDENOQUINOXALINES, AND THEIR KETO DERIVATIVES AND INVESTIGATION OF THEIR STRUCTURES

Prostakov, N. S.,Pleshakov, V. G.,Abedin, Md. Zainul,Kordova, I. R.,Zakharov, V. F.,Zvolinskii, V. P.

, p. 556 - 566 (2007/10/02)

A series of difficultly obtainable and previously unknown methyl homologs of 11H-indenoquinoline, 11H-indenoquinoxaline, and the corresponding 11-keto derivatives were synthesized by new convenient methods, and their structures were investigated.By PMR with lanthanide shift reagents Eu(dpm)3, Pr(dpm)3 and Yb(dpm)3 it was established that the indenoquinolines and ketoindenoquinoxalines do not coordinate with any of the indicated reagents, while the 11-keto derivatives of the indenoquinolines, like those of the indenoquinoxalines, only enter coordination with Yb(dpm)3 at the oxygen atom in the case of the ketoindenoqui nolines and at the N10 nitrogen atom in the case of the indenoquinoxalines.The results from quantum-chemical calculations on the keto derivatives of the indenoquinoline and indenoquinoxaline series are given, and the reasons for the various directions of coordination of Yb(dpm)3 with this type of compound are discussed.
