Check Digit Verification of cas no

The CAS Registry Mumber 1259224-46-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,2,2 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1259224-46:
(9*1)+(8*2)+(7*5)+(6*9)+(5*2)+(4*2)+(3*4)+(2*4)+(1*6)=158
158 % 10 = 8
So 1259224-46-8 is a valid CAS Registry Number.

Synthesis and antibacterial evaluation of 6-azapyrimidines with α-methylene-γ-(4-substituted phenyl)-γ-butyrolactone pharmacophores

Huang, Po-Jui,Lee, Kuan-Han

experimental part, p. 1081 - 1090 (2012/05/05)

A series of 6-substituted 2-[(4-methylene-5- oxo-2-(4-substituted phenyl) tetrahydrofuran-2-yl)methyl]-1, 2,4-triazine-3,5(2H,4H)-diones (5, 6) and 2,4-bis[(4-methylene- 5-oxo-2-(4-substituted phenyl) tetrahydrofuran-2-yl) methyl]-1,2,4-triazine-3,5(2H,4H)-diones (9, 10) were designed, synthesized, and evaluated for antibacterial activity against Gram-positive and Gram-negative microorganisms. The synthesis of these compounds involved the Reformatsky-type reaction between ethyl α-(bromomethyl) acrylate and the proper ketones. Among these compounds, 2-[(4-methylene-5-oxo-2-phenyl tetrahydrofuran-2-yl) methyl]- 1,2,4-triazine-3,5(2H,4H)-dione (5a) is the most active compound and shown the selective inhibition activity against Proteus vulgaris.
