Check Digit Verification of cas no

The CAS Registry Mumber 1159980-80-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,9,9,8 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1159980-80:
(9*1)+(8*1)+(7*5)+(6*9)+(5*9)+(4*8)+(3*0)+(2*8)+(1*0)=199
199 % 10 = 9
So 1159980-80-9 is a valid CAS Registry Number.

Synthesis and anti-inflammatory evaluation of new 1,3,5-triaryl-4,5-dihydro-1H-pyrazole derivatives possessing an aminosulphonyl pharmacophore

Abdellatif, Khaled R. A.,Abdelgawad, Mohamed A.,Elshemy, Heba A. H.,Alsayed, Shahinda S. R.,Kamel, Gehan

, p. 1932 - 1942 (2015)

A novel series of 2-pyrazoline derivatives 13a-l was synthesized via aldol condensation of 4-substituted acetophenones with appropriately substituted aldehydes followed by cyclization of the formed chalcones with 4-hydrazinobenzenesulfonamide hydrochlorid

Synthesis and antimicrobial activities of new 4,6-diaryl- 4,5-dihydro-3-hydroxy-2H-indazoles

Amutha, Parasuraman,Nagarajan, Samuthira

experimental part, p. 428 - 432 (2012/06/30)

A series of new 4,6-diaryl-4,5-dihydro-3-hydroxy-2H-indazoles 5a-5k were synthesized by the cyclization of ethyl 2-oxo-4,6-diarylcyclohex-3-ene carboxylates 4a-4k. The compounds were characterized by IR, 1H NMR, 13C NMR, 2D NMR, and elemental analysis. The synthesized compounds were evaluated for in vitro antibacterial and antifungal activities against Staphylococcus aureus, Escherichia coli, Salmonella typhimurium, Pseudomonas aeruginosa, Candida albicans, Aspergillus niger, Aspergillus flavus, and Rhizopus sp. Most of the compounds exhibited good activity against the tested organisms. Copyright
