135733-31-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 135733-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,3 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135733-31:
(8*1)+(7*3)+(6*5)+(5*7)+(4*3)+(3*3)+(2*3)+(1*1)=122
122 % 10 = 2
So 135733-31-2 is a valid CAS Registry Number.

Synthesis of Furoxans (1,2,5-oxadiazole 2-oxides) from Styrenes and Nitrosonium Tetrafluoroborate in Non-Acidic Media and Mechanistic Study

Matsubara, Ryosuke,Ando, Akihiro,Saeki, Yuta,Eda, Kazuo,Asada, Naoki,Tsutsumi, Tomoaki,Shin, Yong Soon,Hayashi, Masahiko

, p. 1094 - 1105 (2016/07/29)

Diverse furoxans (1,2,5-oxadiazole 2-oxides) were synthesized from the corresponding styrenes using nitrosonium tetrafluoroborate as the nitrosation reagent in pyridine (basic media) or dichloromethane (neutral media). Acid-sensitive functional groups were tolerated under these conditions. The probable reaction mechanism was elucidated. The experimental results support an ionic reaction pathway in contrast to the conventional acidic conditions with a radical mechanism.

Synthesis of oxadiazole-2-oxide analogues as potential antischistosomal agents

Rai, Ganesha,Thomas, Craig J.,Leister, William,Maloney, David J.

body text, p. 1710 - 1713 (2009/07/05)

The synthesis of several 1,2,5-oxadiazole-2-oxide (Furoxan) analogues is described herein. These compounds were prepared in an effort to probe the SAR around the phenyl substituent and oxadiazole core for our studies toward thioredoxin-glutathione reductase (TGR) inhibition and antischistosomal activity.

Pharmacochemistry of the furoxan ring: Recent developments

Calvino,Di Stilo,Fruttero,Gasco,Sorba,Gasco

, p. 321 - 334 (2007/10/02)

In the present work recent results obtained in the pharmacochemistry of the furoxan system are reported. In particular, after a brief description of the salient points of the furoxan chemistry, the synthesis and the properties of a series of Nifedipine and Prazosin analogues, containing this heterocyclic system, are described. Since we observed that a few furoxan derivatives are able to elicit both a dose-dependent rise in platelet cGMP levels and to promote a dose-dependent inhibition of AA-induced [Ca++] rise, and that many substituted furoxans show potent vasodilating and antiaggregatory activity, the possibility of using the furoxan system as a lead in the design of new vasodilators is also discussed.
