Check Digit Verification of cas no

The CAS Registry Mumber 1421520-93-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,5,2 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1421520-93:
(9*1)+(8*4)+(7*2)+(6*1)+(5*5)+(4*2)+(3*0)+(2*9)+(1*3)=115
115 % 10 = 5
So 1421520-93-5 is a valid CAS Registry Number.

Synthesis and antimicrobial activities of a series of 2,5-substituent 1,4-cyclohexanedione derivatives

Liu, Hui-Lian,Wang, Qing-Zhong,Guo, Shu-Hua

, p. 1349 - 1352 (2013/05/09)

A series of 2,5-substituent 1,4-cyclohexanedione derivatives compounds were designed and synthesized. Their structures were identified by elemental analysis, 1H NMR, IR spectra. Their assayed antibacterial (Escherichia coli, Bacillus subtilis) and antifungal (Candida albicans) activities were also evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) method. The results of biological test showed 2,5-dibenzylformate 1,4-cyclohexanedione (11) and 2,5-diformanilide 1,4-cyclohexanedione (12) have favorable antimicrobial activity with MICs of 26.7, 33.6, 24.2 and 32.3 μg/mL against Escherichia coli and Bacillus subtilis, respectively.
