863727-65-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 863727-65-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,3,7,2 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 863727-65:
(8*8)+(7*6)+(6*3)+(5*7)+(4*2)+(3*7)+(2*6)+(1*5)=205
205 % 10 = 5
So 863727-65-5 is a valid CAS Registry Number.

tBuLi-Promoted Intermolecular Regioselective Nucleophilic Addition of Arenes to Diazo Compounds as N-Terminal Electrophiles: Efficient Synthesis of Hydrazine Derivatives

Zhang, Lu,Meng, Xiang-He,Liu, Pei,Chen, Jie,Zhao, Yu-Long

, p. 6137 - 6145 (2017)

The tBuLi-promoted intermolecular direct nucleophilic addition of arenes to diazo compounds as the N-terminal electrophiles has been developed. This reaction proceeds in a completely regioselective manner and is an efficient method for the preparation of hydrazine derivatives in high to excellent yields. This transformation not only provides an efficient approach for aromatic C–N bond formation under transition-metal-free and oxidant-free conditions but also represents a strategy for the 3-amination of pyridines and the dearomatization of indoles.
