Check Digit Verification of cas no

The CAS Registry Mumber 892453-73-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,2,4,5 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 892453-73:
(8*8)+(7*9)+(6*2)+(5*4)+(4*5)+(3*3)+(2*7)+(1*3)=205
205 % 10 = 5
So 892453-73-5 is a valid CAS Registry Number.

Synthesis, characterization, and tuberculostatic activity of novel 2-(4-nitrobenzoyl)hydrazinecarbodithioic acid derivatives

Gobis, Katarzyna,Foks, Henryk,Augustynowicz-Kopec, Ewa,Napiorkowska, Agnieszka,Szczesio, Malgorzata,Olczak, Andrzej,Glowka, Marek L.

, p. 607 - 617 (2012/08/07)

A series of novel S-esters of 2-(4-nitrobenzoyl) hydrazinecarbodithioic acid and S,S'-diesters of (4-nitrobenzoyl)carbonohydrazonodithioic acid were synthesized by reaction of 4-nitrobenzohydrazide and N-methyl- 4-nitrobenzohydrazide with carbon disulfide and alkyl halides in the presence of triethylamine. Novel 5-(4-nitrophenyl)- 1,3,4-oxadiazoles were also obtained. The structures were confirmed by IR, NMR, and mass spectroscopy, and by elemental analysis. All the compounds obtained were screened in vitro for their tuberculostatic activity. Promising preliminary results were obtained for some of the compounds. The crystal structure of the most active compound was determined. The Author(s) 2012.
