128588-63-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128588-63-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,8 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128588-63:
(8*1)+(7*2)+(6*8)+(5*5)+(4*8)+(3*8)+(2*6)+(1*3)=166
166 % 10 = 6
So 128588-63-6 is a valid CAS Registry Number.

Iron-Catalyzed Radical Cycloaddition of 2H-Azirines and Enamides for the Synthesis of Pyrroles

Zhao, Mi-Na,Ren, Zhi-Hui,Yang, De-Suo,Guan, Zheng-Hui

, p. 1287 - 1290 (2018)

A novel and efficient Fe-catalyzed radical cycloaddition of 2H-azirines and enamides for the synthesis of substituted pyrroles has been developed. The radical cycloaddition reaction proceeded through a conceptually new Fe(II)-catalyzed homolytic cleavage of C-N bond of 2H-azirines sequential radical cyclization with enamides. The reaction used readily available starting materials, tolerated various functional groups, and afforded valuable triaryl-substituted pyrroles in good to high yields under mild reaction conditions.

ortho Effect on the Nitrosation of the 2,3-Diphenyl-5-(2-methoxyphenyl)pyrrole

Ceraulo, Leopoldo,Agozzino, Pasquale,Ferrugia, Mirella,Sprio, Vincenco

, p. 255 - 258 (2007/10/02)

A comparison of the behaviour on the nitrosation of the isomers 5-(2-methoxyphenyl)- (1a), 5-(3-methoxyphenyl)- (1b) and 5-(4-methoxyphenyl)-2,3-diphenylpyrroles (1c) carried out in the usual way with iso-amyl nitrite in a solution of sodium ethoxide in e
