60420-81-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 60420-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,4,2 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 60420-81:
(7*6)+(6*0)+(5*4)+(4*2)+(3*0)+(2*8)+(1*1)=87
87 % 10 = 7
So 60420-81-7 is a valid CAS Registry Number.

Efficient copper-catalyzed S-arylation of thiols with aryl bromides and chlorides

Li, Yaming,Li, Xiaoying,Wang, Huifeng,Chen, Tao,Xie, Yusheng

supporting information; experimental part, p. 3602 - 3608 (2010/12/19)

An efficient copper-catalyzed system for C-S cross-coupling of aromatic thiols with aryl bromides and chlorides has been developed using 1,2,3,4-tetrahydroquinoline-8-ol as a ligand. It is noteworthy that this method is proved to be especially effective for aryl bromides with electron-donating groups. By this protocol, a variety of thioethers as well as symmetrical and unsymmetrical bis-thioethers are obtained in excellent yields with an exceptional level of functional group tolerance and high chemoselectivity.
