Check Digit Verification of cas no

The CAS Registry Mumber 19133-53-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,1,3 and 3 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19133-53:
(7*1)+(6*9)+(5*1)+(4*3)+(3*3)+(2*5)+(1*3)=100
100 % 10 = 0
So 19133-53-0 is a valid CAS Registry Number.

Copper-Catalyzed Three-Component One-Pot Synthesis of Aryl Sulfides with Sulfur Powder under Aqueous Conditions

Xiao, Fuhong,Chen, Shuqing,Li, Cheng,Huang, Huawen,Deng, Guo-Jun

supporting information, p. 3881 - 3886 (2016/12/16)

A copper-catalyzed three-component (arenes, iodohydrocarbon, and sulfur powder) synthesis of substituted aryl sulfides has been developed. Water is used as the green solvent in a simple and environmentally friendly procedure. Various functional groups attached to the substrates were well tolerated in this process to afford the corresponding products in moderate to good yields. (Figure presented.).

Silver ion mediated in situ synthesis of mixed diaryl sulfides from diaryl disulfides

Gogoi, Prasanta,Gogoi, Sandhya R.,Kalita, Mukul,Barman, Pranjit

, p. 873 - 877 (2013/05/21)

The AgNO3-mediated in situ scission of aromatic disulfides in the presence of electron-rich aromatic compounds results in the efficient synthesis of diaryl sulfides. Key features of this new methodology are high yields of aromatic and heteroaromatic sulfides, mild reaction conditions, simplicity, simple workup, and avoiding foul-smelling reactants like thiols.
