Check Digit Verification of cas no

The CAS Registry Mumber 1569098-53-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,0,9 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1569098-53:
(9*1)+(8*5)+(7*6)+(6*9)+(5*0)+(4*9)+(3*8)+(2*5)+(1*3)=218
218 % 10 = 8
So 1569098-53-8 is a valid CAS Registry Number.

One-pot DBU-promoted synthesis of hydroacridinones and spirohexahydropyrimidines

Neochoritis, Constantinos G.,Eleftheriadis, Nicolaos,Tsiantou, Arianna,Stephanidou-Stephanatou, Julia,Tsoleridis, Constantinos A.

, p. 2768 - 2772 (2013)

The potential hydroacridinone synthesis using simple and inexpensive starting materials, namely 1,3-dicarbonyl compounds, anilines, formaldehyde and DBU as a stoichiometric base was explored. As a result, from the reaction of 1,3-cyclohexanedione and dimedone tetrahydroacridinones were the main reaction products along with small yields of their oxidation products, the dihydroacridinones, whereas in the case of 2-acetylcyclohexanone spirohexahydropyrimidines were isolated in very good yields. Plausible mechanistic schemes for the formation of all products are proposed. Georg Thieme Verlag Stuttgart New York.
