3274-66-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3274-66-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,7 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3274-66:
(6*3)+(5*2)+(4*7)+(3*4)+(2*6)+(1*6)=86
86 % 10 = 6
So 3274-66-6 is a valid CAS Registry Number.

Catalyst-Dependent Chemoselective Formal Insertion of Diazo Compounds into C?C or C?H Bonds of 1,3-Dicarbonyl Compounds

Liu, Zhaohong,Sivaguru, Paramasivam,Zanoni, Giuseppe,Anderson, Edward A.,Bi, Xihe

, (2018)

A catalyst-dependent chemoselective one-carbon insertion of diazo compounds into the C?C or C?H bonds of 1,3-dicarbonyl species is reported. In the presence of silver(I) triflate, diazo insertion into the C(=O)?C bond of the 1,3-dicarbonyl substrate leads

Iron-catalyzed tandem one-pot addition and cyclization of the blaise reaction intermediate and nitroolefins: Synthesis of substituted NH-pyrroles from nitriles

Zhao, Mi-Na,Liang, Hao,Ren, Zhi-Hui,Guan, Zheng-Hui

, p. 221 - 226 (2013/03/13)

The iron-catalyzed addition and cyclization of the Blaise reaction intermediate and nitroolefins to synthesize highly functionalized NH-pyrroles in a tandem one-pot manner from nitriles has been developed. This reaction shows good functional group tolerance and affords a broad spectrum of substituted NH-pyrroles in good yields. Copyright
