Check Digit Verification of cas no

The CAS Registry Mumber 2452-76-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,5 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2452-76:
(6*2)+(5*4)+(4*5)+(3*2)+(2*7)+(1*6)=78
78 % 10 = 8
So 2452-76-8 is a valid CAS Registry Number.

REACTIONS OF POLYMETHINE DYES. I. SYNTHESIS OF THE PSEUDOBASES OF POLYMETHINE DYES AND THEIR TRANSFORMATIONS

Vompe, A. F.,Ivanova, L. V.,Meskhi, L. M.,Monich, N. V.,Raikhina, R. D.

, p. 529 - 537 (2007/10/02)

Nonsalt-like benzene-soluble pseudobases are formed in the reaction of polymethine dyes with sodium alcoholates.The presence of ionized and un-ionized forms of the pseudobases was established by electronic absorption spectra in aprotic solvents.Solutions of these compounds in alcohols only contain the ionized forms; the unionized form predominates in benzene solutions.The action of various acids on the pseudobases leads to the production of polymethine dyes with the respective anions.
