180639-95-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 180639-95-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,6,3 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 180639-95:
(8*1)+(7*8)+(6*0)+(5*6)+(4*3)+(3*9)+(2*9)+(1*5)=156
156 % 10 = 6
So 180639-95-6 is a valid CAS Registry Number.

Enhancing the synthetic utility of 3-haloaryne intermediates by their efficient Generation from readily synthesizable ortho-iodoaryl triflate-type precursors

Yoshida, Suguru,Nagai, Akira,Uchida, Keisuke,Hosoya, Takamitsu

supporting information, p. 733 - 736 (2017/09/01)

Generation of 3-haloarynes from o-iodoaryl triflate-type precursors is reported. The method enables the generation of 3-fluorobenzyne with significantly high electrophilicity at -78 °C, allowing the formation of a three-component-coupled product between 3

2,5,7-Trisubstituted benzo[b]furans through a copper- and/or palladium-catalyzed assembly and functionalization process

Arcadi, Antonio,Blesi, Federico,Cacchi, Sandro,Fabrizi, Giancarlo,Goggiamani, Antonella

, p. 5149 - 5152 (2011/10/12)

A straightforward approach to the synthesis of 2,5,7-trisubstituted benzo[b]furans from 2-bromo- and 2-chloro-6-iodo-4-substituted phenols through a consecutive copper- and/or palladium-catalyzed assembly and functionalization process is described. Functionalization at the C(7) position is carried out by Suzuki-Miyaura cross-coupling and C-N bond forming reactions.
