861374-56-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 861374-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,3,7 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 861374-56:
(8*8)+(7*6)+(6*1)+(5*3)+(4*7)+(3*4)+(2*5)+(1*6)=183
183 % 10 = 3
So 861374-56-3 is a valid CAS Registry Number.

One-pot method for regioselective bromination and sequential carbon-carbon bond-forming reactions of allylic alcohol derivatives

Kutsumura, Noriki,Matsubara, Yusuke,Niwa, Kentaro,Ito, Ai,Saito, Takao

, p. 3337 - 3346 (2013/06/27)

An efficient one-pot method for the regioselective bromination of allylic alcohol derivatives (two-step reaction sequence) followed by Sonogashira, Negishi, or Suzuki-Miyaura coupling reactions in the same reaction vessel (three-step reaction sequence) ha

Novel one-pot method for chemoselective bromination and sequential sonogashira coupling

supporting information; experimental part, p. 3316 - 3319 (2010/10/19)

(Equation Presented). An efficient one-pot method for bromination- elimination of allyl alcohol derivatives and sequential Sonogashira coupling has been developed. A highlight of the method is chemoselective DBU-promoted elimination of vicinal dibromoalka

1,2-Dibromoalkanes into alkynes by elimination reaction under DBU conditions and their application to total synthesis of sapinofuranone B

Kutsumura, Noriki,Yokoyama, Tadashi,Ohgiya, Tadaaki,Nishiyama, Shigeru

, p. 4133 - 4136 (2007/10/03)

Treatment of 1,2-dibromoalkanes with DBU effected an elimination reaction, leading to the alkynes. Oxygen substitution at the C3 position plays a critical role to abstract protons by inductive effects. By the application of this protocol, a total synthesi
