1276088-25-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1276088-25-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,6,0,8 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1276088-25:
(9*1)+(8*2)+(7*7)+(6*6)+(5*0)+(4*8)+(3*8)+(2*2)+(1*5)=175
175 % 10 = 5
So 1276088-25-5 is a valid CAS Registry Number.

Zinc-promoted cyclization of tosylhydrazones and 2-(dimethylamino)malononitrile: An efficient strategy for the synthesis of substituted 1-tosyl-1: H -pyrazoles

Zhang, Bang-Hong,Lei, Lin-Sheng,Liu, Si-Zhan,Mou, Xue-Qing,Liu, Wei-Ting,Wang, Shao-Hua,Wang, Jie,Bao, Wen,Zhang, Kun

, p. 8545 - 8548 (2017)

A Zn(OTf)2-promoted cyclization reaction of tosylhydrazones with 2-(dimethylamino)malononitrile has been successfully developed providing an efficient strategy for the synthesis of substituted 1-tosyl-1H-pyrazoles.

Method for synthesis of substituted 1-sulfonyl-1H-pyrazole

-

Paragraph 0057; 0058; 0059; 0060; 0061, (2017/10/07)

The invention discloses a method for synthesis of substituted 1-sulfonyl-1H-pyrazole, and aims to provide a method for synthesis of 1-sulfonyl-1H-pyrazole, the method has the advantages of simple and easily available starting materials, high yield and easy operation, the method is characterized in that sulfonyl hydrazone, N, N-dimethylmalononitrile and a Lewis acid catalyst are in turn added into an organic solvent for heating refluxing reaction to obtain the substituted 1-sulfonyl-1H-pyrazole, and the method belongs to the organic synthesis technical field.

A new synthesis of pyrazoles through a Lewis acid catalyzed union of 3-ethoxycyclobutanones with monosubstituted hydrazines

Shan, Gang,Liu, Pengfei,Rao, Yu

supporting information; experimental part, p. 1746 - 1749 (2011/05/12)

A new efficient and convenient approach toward the synthesis of pyrazoles is described. Through a Lewis acid catalyzed union of 3-ethoxycyclobutanones with monosubstituted hydrazines, a variety of pyrazole derivatives were prepared readily at ambient temp
