135659-89-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 135659-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,6,5 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 135659-89:
(8*1)+(7*3)+(6*5)+(5*6)+(4*5)+(3*9)+(2*8)+(1*9)=161
161 % 10 = 1
So 135659-89-1 is a valid CAS Registry Number.

Formal [4 + 1] Annulation of α-Arylhydrazonoketones and Dimethylsulfoxonium Methylide: One-pot Synthesis of Substituted Pyrazoles and Dihydropyrazoles

Zhang, Qian,Yu, Mangfei,Yuan, Jingwen,Zhang, Rui,Liang, Yongjiu,Tian, Jiamei,Dong, Dewen

, p. 6036 - 6041 (2016/07/26)

A formal [4 + 1] annulation of readily available α-arylhydrazonoketones and trimethylsulfoxonium iodide in the presence of cesium carbonate is described involving a sequential Corey-Chaykovsky reaction and intramolecular nucleophilic cyclization process. Substituted pyrazoles were obtained exclusively from the reactions of α-arylhydrazono-β-oxo-amides and trimethylsulfoxonium iodide in moderate to good yields, whereas the reactions of α-arylhydrazono-β-oxo-ketone/α-arylhydrazono- β-oxo-ester afforded the corresponding dihydropyrazoles in good yields.
