1236063-59-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1236063-59-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,6,0,6 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1236063-59:
(9*1)+(8*2)+(7*3)+(6*6)+(5*0)+(4*6)+(3*3)+(2*5)+(1*9)=134
134 % 10 = 4
So 1236063-59-4 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

TBAF-promoted dehydrobrominations of vicinal dibromides having an adjacent O-functional group

Kutsumura, Noriki,Kubokawa, Keisuke,Saito, Takao

experimental part, p. 2717 - 2720 (2010/12/25)

Regioselective HBr elimination of vicinal dibromides having an adjacent oxygen functional group to give the corresponding 2-bromoalk-1-enes was controlled using 1.1 equivalents of TBAF. Two-step elimination to give the corresponding alkynes was controlled using 5.0 equivalents of TBAF. High yield and high selectivity require the presence of an oxygen functional group at the neighboring position of the elimination site.
