Check Digit Verification of cas no

The CAS Registry Mumber 181418-30-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,4,1 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 181418-30:
(8*1)+(7*8)+(6*1)+(5*4)+(4*1)+(3*8)+(2*3)+(1*0)=124
124 % 10 = 4
So 181418-30-4 is a valid CAS Registry Number.

Synthesis of novel halobenzyloxy and alkoxy 1,2,4-triazoles and evaluation for their antifungal and antibacterial activities

Wan, Kun,Zhou, Cheng-He

experimental part, p. 2003 - 2010 (2010/12/19)

A new class of halobenzyloxy or alkoxy 1,2,4-triazoles and their hydrochlorides were synthesized through cyclization starting from commercially available phenylhydrazine. The structures were characterized by MS, IR and 1H NMR spectra as well as elemental analyses. All the synthesized compounds were screened for their antibacterial activities in vitro against Staphylococcus aureus (ATCC29213), methicillin-resistant Staphylococcus aureus (N315), Bacillus subtilis, Escherichia coli (ATCC25922), Pseudomonas aeruginosa, Shigella dysenteriae, Eberthella typhosa, and antifungal activities against Candida albicans (ATCC76615), Aspergillus fumigatus by broth microdilution assay method. The results of preliminary bioassay indicated that 3-(2,4- difluorobenzyloxy)-1-phenyl-1H-1,2,4-triazole hydrochloride exhibited the best inhibitory activity with an MIC value of 56.25 μM against P. aeruginosa superior to Chloramphenicol, and showed comparable activity with Chloramphenicol against E. coli (ATCC25922).
