Check Digit Verification of cas no

The CAS Registry Mumber 1042717-68-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,7,1 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1042717-68:
(9*1)+(8*0)+(7*4)+(6*2)+(5*7)+(4*1)+(3*7)+(2*6)+(1*8)=129
129 % 10 = 9
So 1042717-68-9 is a valid CAS Registry Number.

A very active Cu-catalytic system for the synthesis of aryl, heteroaryl, and vinyl sulfides

Kabir, M. Shahjahan,Lorenz, Michael,Van Linn, Michael L.,Namjoshi, Ojas A.,Ara, Shamim,Cook, James M.

experimental part, p. 3626 - 3643 (2010/07/14)

Figure presented cis-1,2-Cyclohexanediol (L3) has been shown to be an efficient and versatile bidentate O-donor ligand that provides a highly active Cu-catalytic system. It was more effective than diols such as trans-1,2-cyclohexanediol or ethylene glycol. This commercially available cis-1,2-cyclohexanediol ligand facilitated the Cu-catalyzed cross-coupling reactions of alkyl, aryl, or heterocyclic thiols with either alkyl, aryl, heterocyclic, or substituted vinyl halides. This new catalytic system promoted the mild and efficient stereo- and regiospecific synthesis of biologically important vinyl sulfides. The yields obtained using electron-rich substituted vinyl sulfides with this catalyst system are generally 75-98%. Most importantly, this singular catalyst system is extremely versatile and provides entry into a wide range of sulfides. This method is particularly noteworthy given its mild reaction conditions, simplicity, generality, and exceptional level of functional group tolerance.
