Check Digit Verification of cas no

The CAS Registry Mumber 1040281-85-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,2,8 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1040281-85:
(9*1)+(8*0)+(7*4)+(6*0)+(5*2)+(4*8)+(3*1)+(2*8)+(1*5)=103
103 % 10 = 3
So 1040281-85-3 is a valid CAS Registry Number.

Iridium-catalyzed borylation of thiophenes: versatile, synthetic elaboration founded on selective C-H functionalization

Chotana, Ghayoor A.,Kallepalli, Venkata A.,Maleczka Jr., Robert E.,Smith III, Milton R.

, p. 6103 - 6114 (2008/12/20)

Iridium-catalyzed borylation has been applied to various substituted thiophenes to synthesize poly-functionalized thiophenes in good to excellent yields. Apart from common functionalities compatible with iridium-catalyzed borylations, additional functional group tolerance to acyl (COMe) and trimethylsilyl (TMS) groups was also observed. High regioselectivities were observed in borylation of 3- and 2,5-di-substituted thiophenes. Electrophilic aromatic C-H/C-Si bromination on thiophene boronate esters is shown to take place without breaking the C-B bond, and one-pot C-H borylation/Suzuki-Miyaura cross-coupling has been accomplished on 2- and 3-borylated thiophenes.
