306298-83-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 306298-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,6,2,9 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 306298-83:
(8*3)+(7*0)+(6*6)+(5*2)+(4*9)+(3*8)+(2*8)+(1*3)=149
149 % 10 = 9
So 306298-83-9 is a valid CAS Registry Number.

Synthesis, analgesic, anti-inflammatory and antimicrobial studies of 2,4-dichloro-5-fluorophenyl containing thiazolotriazoles

Karthikeyan, Mari Sithambaram

scheme or table, p. 827 - 833 (2009/09/08)

A series of 2,4-dichloro-5-fluorophenyl containing thiazolotriazoles (1) were synthesized starting from 3-(2,4-dichloro-5-fluorophenyl)-4H-1,2,4-triazole-3-thiol (5). The newly synthesized compounds were characterized by IR, 1H NMR, mass and el

Fluorine containing heterocyclic compounds: Synthesis of 6-substituted-2-substituted-aryl-1,2,4-triazolo[5,1-b] 1,3,5-thiadiazin-7-one derivatives

Liu, Suyou,Qian, Xuhong,Song, Gonghua,Chen, Jing,Chen, Weidong

, p. 111 - 115 (2007/10/03)

A group of heterocylic compounds of condensed triazole-thiadiazinone derivatives containing fluorine (IIIa-h) were obtained in good yields by the reactions of the corresponding 3-aryl-5-mercapto-1,2,4-triazole (IIa-d) with N-substituted-N-chloromethyl carbamoyl chloride (I) in the presence of potassium carbonate in N,N-dimethylformamide at room temperature. Cyclization of 3-(2,3,5-trifluoro-4-methoxyl)phenyl-5-mercapto-1,2,4-triazole (IIe) with I was difficult due to an intermolecular hydrogen bond of IIe. The structures of the compounds synthesized were confirmed by IR, MS, 1H NMR and elemental analyses. Fungicidal and insecticidal activities of these compounds were also studied.
