Check Digit Verification of cas no

The CAS Registry Mumber 1242674-03-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,6,7 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1242674-03:
(9*1)+(8*2)+(7*4)+(6*2)+(5*6)+(4*7)+(3*4)+(2*0)+(1*3)=138
138 % 10 = 8
So 1242674-03-8 is a valid CAS Registry Number.

Copper-catalyzed thiolation of the Di- or trimethoxybenzene arene C-H bond with disulfides

Zhang, Shouhui,Qian, Pengcheng,Zhang, Manli,Hu, Maolin,Cheng, Jiang

experimental part, p. 6732 - 6735 (2010/12/19)

A CuI-catalyzed direct access to sulfides from disulfides via C-H bond cleavage of di- or trimethoxybenzene is described. The procedure utilizes O 2 as a clean and cheap oxidant. Direct selenation of the C-H bond also took place under this procedure. Furthermore, the system enables the use of two RS in (RS)2. Thus, it represents an atom-economical procedure for the synthesis of sulfides and selenides.
