36629-61-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 36629-61-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,6,2 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 36629-61:
(7*3)+(6*6)+(5*6)+(4*2)+(3*9)+(2*6)+(1*1)=135
135 % 10 = 5
So 36629-61-5 is a valid CAS Registry Number.

Enantioselective Arylation of 3-Carboxamide Oxindoles with Quinone Monoimines and Synthesis of Chiral Spirooxindole-benzofuranones

Chen, Hui,Liu, Hui,Zhao, Si-Han,Cheng, Shao-Bing,Xu, Xiao-Ying,Yuan, Wei-Cheng,Zhang, Xiao-Mei

supporting information, p. 1067 - 1072 (2019/05/24)

A highly enantioselective arylation of 3-carboxamide oxoindoles with quinone monoimines is described. Various 3-aryl-3-carboxamide oxindoles with an all-carbon quaternary center were obtained in moderate to good yields (up to 99%) with moderate to good enantioselectivities (up to 98%) in the presence of a bifunctional thiourea-tertiary amine catalyst. The absolute configuration of one product was determined by an X-ray crystal structural analysis and the absolute configurations of the other products can be assigned by analogy. Moreover, several chiral spirooxindole-benzofuranones were synthesized from the 3-aryl-3-carboxamide oxindoles in moderate yields with moderate to good enantioselectivities.
