1281970-70-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1281970-70-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,1,9,7 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1281970-70:
(9*1)+(8*2)+(7*8)+(6*1)+(5*9)+(4*7)+(3*0)+(2*7)+(1*0)=174
174 % 10 = 4
So 1281970-70-4 is a valid CAS Registry Number.

Copper-Catalyzed Oxidative Cross-Coupling of Electron-Deficient Polyfluorophenylboronate Esters with Terminal Alkynes

Liu, Zhiqiang,Budiman, Yudha P.,Tian, Ya-Ming,Friedrich, Alexandra,Huang, Mingming,Westcott, Stephen A.,Radius, Udo,Marder, Todd B.

, p. 17267 - 17274 (2020/12/01)

We report herein a mild procedure for the copper-catalyzed oxidative cross-coupling of electron-deficient polyfluorophenylboronate esters with terminal alkynes. This method displays good functional group tolerance and broad substrate scope, generating cro

Decyl(tri- tert -butyl)phosphonium tetrafluoroborate/palladium acetate: An effective catalyst for cross-coupling reaction of arylbromides with phenylacetylene in copper-free conditions

Ermolaev, Vadim,Miluykov, Vasiliy,Arkhipova, Daria,Zvereva, Elena,Sinyashin, Oleg

, p. 168 - 170 (2013/07/05)

Abstract The phosphonium salts with sterically hindered cation and noncoordinating anion can be used as phase-transfer reagent in the Sonogashira cross-coupling reaction allowing copper- and amine-free protocol. The reactions proceed under mild conditions
