Check Digit Verification of cas no

The CAS Registry Mumber 1220125-56-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,1,2 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1220125-56:
(9*1)+(8*2)+(7*2)+(6*0)+(5*1)+(4*2)+(3*5)+(2*5)+(1*6)=83
83 % 10 = 3
So 1220125-56-3 is a valid CAS Registry Number.

An Expedient, Direct, Three-Component Approach for the Synthesis of 4-Thioarylpyrroles

Anandan, Sambandam,Neelamegam, Chinnaraj,Rajeshkumar, Venkatachalam

supporting information, p. 4023 - 4033 (2019/10/28)

A three-component strategy for the synthesis of 4-thioarylpyrroles from 1,4-enediones, thiols, and ammonium formate in one-pot has been developed. The reaction proceeds through the sequential thiol-Michael/Paal-Knorr reaction of 1,4-enediones with the for

Heterogeneous synthesis of 1,4-enediones and 1,4-diketones with manganese oxide molecular sieves OMS-2 as a recyclable catalyst

Meng, Xu,Zhang, Jinqi,Chen, Gexin,Chen, Baohua,Zhao, Peiqing

, p. 239 - 242 (2015/07/27)

An efficient manganese oxide octahedral molecular sieves OMS-2-catalyzed chemoselective synthesis of 1,4-enediones and 1,4-diketones from 1,3-dicarbonyls and α-iodoacetophenones is described. The present catalytic system can be applied in one-pot, three-c

Formation of unsymmetrical 1,4-enediones via A focusing domino strategy: Cross-coupling of 1,3-dicarbonyl compounds and methyl ketones or terminal aryl alkenes

Gao, Meng,Yang, Yan,Wu, Yan-Dong,Deng, Cong,Cao, Li-Ping,Meng, Xiang-Gao,Wu, An-Xin

supporting information; experimental part, p. 1856 - 1859 (2010/10/03)

A highly efficient synthesis of unsymmetrical 1,4-enediones from 1,3-dicarbonyl compounds and methyl ketones or terminal aryl alkenes has been developed via a focusing domino strategy. Simple and readily available starting materials, mild reaction conditions, and a very simple operation are advantages of the reaction, which allow straightforward synthesis of a variety of unsymmetrical 1,4-enediones.
