Check Digit Verification of cas no

The CAS Registry Mumber 19717-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,1 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19717-02:
(7*1)+(6*9)+(5*7)+(4*1)+(3*7)+(2*0)+(1*2)=123
123 % 10 = 3
So 19717-02-3 is a valid CAS Registry Number.

A Novel Method for the Direct Synthesis of Symmetrical and Unsymmetrical Sulfides and Disulfides from Aryl Halides and Ethyl Potassium Xanthogenate

Soleiman-Beigi,Arzehgar

supporting information, p. 986 - 992 (2018/02/09)

An efficient and new method for the synthesis of disulfides and sulfides via the reaction of aryl halides with ethyl potassium xanthogenate in the presence of MOF-199 is described. O -Ethyl- S -aryl carbonodithioate has a key role as an intermediate in this procedure; it was converted into symmetrical diaryl disulfides in DMF. Additionally, this could be applied to the synthesis of unsymmetrical aryl alkyl(aryl′) disulfides by the reaction with S -alkyl(aryl) sulfurothioates (Bunte salts) as well as unsymmetrical aryl alkyl(aryl′) sulfides in DMSO.

Synthesis of unsymmetrical sulfides using ethyl potassium xanthogenate and recyclable copper catalyst under ligand-free conditions

Akkilagunta, Vijay Kumar,Kakulapati, Rama Rao

supporting information; experimental part, p. 6819 - 6824 (2011/10/09)

The synthesis of unsymmetrical sulfides has been achieved in good to excellent yields with inexpensive ethyl potassium xanthogenate via cross-coupling reaction using recyclable CuO nanoparticles under ligand-free conditions.The copper oxide nanoparticles can be recovered and reused up to five cycles without loss of activity.

Reactions of Aromatic Diazonium Salts with Butyl Vinyl Ether in the Presence of Potassium O-Alkyl Dithiocarbonates

Grishchuk,Kudrik,Gorbovoi,Ganushchak

, p. 1482 - 1485 (2007/10/03)

Arenediazonium tetrafluoroborates, sulfates, and nitrates react with butyl vinyl ether in aqueous acetone in the presence of potassium O-alkyl dithiocarbonates to yield O-alkyl S-(2-aryl-1-butoxyethyl) dithiocarbonates (Alk = Et, Bu, t-Bu). The reaction is accompanied by formation of O-alkyl S-aryl dithiocarbonates, which are the main products of the reaction of arenediazonium salts with potassium O-alkyl dithiocarbonates in the absence of unsaturated compound.
