6836-83-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6836-83-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,3 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6836-83:
(6*6)+(5*8)+(4*3)+(3*6)+(2*8)+(1*3)=125
125 % 10 = 5
So 6836-83-5 is a valid CAS Registry Number.

Base initiated aromatization/CO bond formation: A new entry to O-pyrazole polyfluoroarylated ethers

Tang, Xiangyang,Chang, Jing,Liu, Cuibo,Zhang, Bin

, p. 6534 - 6537 (2015/01/08)

A base initiated intermolecular SNAr reaction of pyrazolones with polyfluoroarenes was developed. The process involved the isomerization aromatization of pyrazolone followed by the CO bond formation via the selective CF bond cleavage. With this strategy, a wide range of O-pyrazole polyfluoroarylated ethers bearing diverse functional groups were synthesized in mild to good yields. Additionally, our method was also applied to the isoxazol substrates.

Microwave-assisted synthesis of substituted pyrazolones under solvent-free conditions

Mojtahedi, Mohammad M.,Jalali, Mohammad R.,Saeed Abaee,Bolourtchian, Mohammad

, p. 225 - 228 (2007/10/03)

Condensation of hydrazine derivatives with various β-keto esters under solvent-free conditions using microwave irradiation leads to very rapid formation of pyrazolones with good to excellent yields.
