Check Digit Verification of cas no
The CAS Registry Mumber 46898-00-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,6,8,9 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 46898-00:
(7*4)+(6*6)+(5*8)+(4*9)+(3*8)+(2*0)+(1*0)=164
164 % 10 = 4
So 46898-00-4 is a valid CAS Registry Number.

PREPARATION AND IMINE-ENAMINE TAUTOMERISM OF 4,6-DIPHENYL-1,2-DIHYDROPYRIMIDINE
Weis, Alexander L.,Vishkautsan, Rosita
, p. 1773 - 1776 (1984)
4,6-Diphenyl-1,2-dihydropyrimidine was prepared by LiAlH4 reduction of 4,6-diphenylpyrimidin-2(1H)-one or 4,6-diphenylpyrimidine.Using 1H and 13C NMR, it was shown that in CDCl3 the product exists in tautomeric equilibrium with 4,6-diphenyl-2,5-dihydropyr
