20641-27-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20641-27-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,4 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20641-27:
(7*2)+(6*0)+(5*6)+(4*4)+(3*1)+(2*2)+(1*7)=74
74 % 10 = 4
So 20641-27-4 is a valid CAS Registry Number.

The palladium-catalyzed O-allylation of α-hydroxyphosphonates and α-hydroxyamides obtained from Pudovik and Passerini multicomponent reactions has allowed interesting and highly straightforward access to a variety of building blocks for product diversific

Palladium-catalysed O-Allylation of α-Hydroxyphosphonates: An Expedient Entry into Phosphono-oxaheterocycles

Kerim, Mansour Dolé,Cattoen, Martin,Fincias, Nicolas,Dos Santos, Aurélie,Arseniyadis, Stellios,El Ka?m, Laurent

supporting information, p. 449 - 454 (2017/12/04)

We report here an unprecedented palladium-catalysed O-allylation of α-hydroxyphosphonates. The method was eventually included in a sequential Pudovik/Tsuji-Trost type O-allylation/Ring-Closing Metathesis to afford a variety of phosphorylated heterocycles

Copper-catalyzed synthesis of α-hydroxy phosphonates from H-phosphonates and alcohols or ethers

Zhao, Zengxiang,Xue, Wanhua,Gao, Yuxing,Tang, Guo,Zhao, Yufen

supporting information, p. 713 - 716 (2013/05/09)

Easy PC: α-Hydroxy phosphonates were synthesized by copper/tert-butyl hydroperoxide (TBHP)-catalyzed oxidative addition reactions of H-phosphonates with alcohols or ethers. Diverse α-hydroxy phosphonates were obtained from substituted benzyl alcohols or alkyl alcohols and alkyl ethers in moderate to good yields. Copyright
