130970-51-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130970-51-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,9,7 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130970-51:
(8*1)+(7*3)+(6*0)+(5*9)+(4*7)+(3*0)+(2*5)+(1*1)=113
113 % 10 = 3
So 130970-51-3 is a valid CAS Registry Number.

Chiral Bicyclo[2.2.2]octane-Fused CpRh Complexes: Synthesis and Potential Use in Asymmetric C?H Activation

Li, Guozhu,Yan, Xiaoqiang,Jiang, Jijun,Liang, Hao,Zhou, Chao,Wang, Jun

, p. 22436 - 22440 (2020/10/15)

A new class of chiral cyclopentadienyl rhodium(I) complexes (CpRhI) bearing C2-symmetric chiral bridged-ring-fused Cp ligands was prepared. The complexes were successfully applied to the asymmetric C?H activation reaction of N-methoxybenzamides with quinones, affording a series of chiral hydrophenanthridinones in up to 82 % yield with up to 99 % ee. Interestingly, structure analysis reveals that the side wall of the optimal chiral CpRhI catalyst is vertically more extended, horizontally less extended, and closer to the metal center in comparison with the classic binaphthyl and spirobiindanyl CpRhI complexes, and may thus account for its superior catalytic performance.

Syntheses of novel chiral 2,5-dialkyl-7-azabicyclo[2.2.1]heptanes and 2,5-dialkyl-7-thiobicyclo[2.2.1]heptanes

Xiao, Dengming,Zhang, Zhaoguo,Jiang, Qiongzhong,Zhang, Xumu

, p. 5331 - 5334 (2007/10/03)

New C2-symmetric chiral amines with a rigid bicyclic framework have been synthesized via hydrogenation of monoazides catalyzed by 5% Pd/C in methanol. Enantiomerically pure 2,5-dialkyl-7-thiobicyclo[2.2.1]heptanes were made from readily available materials.
