Check Digit Verification of cas no

The CAS Registry Mumber 5197-20-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,9 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5197-20:
(6*5)+(5*1)+(4*9)+(3*7)+(2*2)+(1*0)=96
96 % 10 = 6
So 5197-20-6 is a valid CAS Registry Number.

Potential anticonvulsants. VI: Condensation of isatins with cyclohexanone and other cyclic ketones

Pajouhesh,Parson,Popp

, p. 318 - 321 (1983)

Cyclohexanone, substituted cyclohexanones, and other cycloalkanones have been condensed with isatin and substituted isatins to give a series of new 3-hydroxy-3-substituted oxindoles. A number of these 3-hydroxyoxindoles possess anticonvulsant activity.

"on Water" Catalytic Aldol Reaction between Isatins and Acetophenones: Interfacial Hydrogen Bonding and Enamine Mechanism

Han, Jinsong,Zhang, Jin-Lei,Zhang, Wei-Qiang,Gao, Ziwei,Xu, Li-Wen,Jian, Yajun

, p. 7642 - 7651 (2019/06/17)

"On water" catalytic aldol reaction catalyzed by polyetheramine (D230) has been developed for easy access to 3-substituted 3-hydroxyindolin-2-ones through the reaction between various substituted isatins and acetophenones/cyclic ketones in high yields under room temperature. Systematic mechanism investigation uncovers the secret for the on water catalytic aldol reaction: comparison of the heterogeneous and homogeneous reaction circumstances with yields of 95 and 20%, respectively, indicates the on-water reaction dominating; interfacial hydrogen bonding between isatin with H2O is tested based on the downfield shift of the C2 and C3's 13C NMR signals when water was added to the CDCl3 solution of isatin; Lewis base polyetheramine D230 catalyzes the aldol reaction via the enamine mechanism verified by in situ NMR and ESI-MS analysis.
