Check Digit Verification of cas no

The CAS Registry Mumber 137117-06-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,1 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 137117-06:
(8*1)+(7*3)+(6*7)+(5*1)+(4*1)+(3*7)+(2*0)+(1*6)=107
107 % 10 = 7
So 137117-06-7 is a valid CAS Registry Number.

2-Oxindole Acts as a Synthon of 2-Aminobenzoyl Anion in the K2CO3-Catalyzed Reaction with Enones: Preparation of 1,4-Diketones Bearing an Amino Group and Their Further Transformations

Miao, Chun-Bao,Zeng, Yu-Mei,Shi, Tong,Liu, Rui,Wei, Peng-Fei,Sun, Xiao-Qiang,Yang, Hai-Tao

, p. 43 - 50 (2016)

A convenient approach for the synthesis of 1,4-diketones bearing an amino group has been developed through the K2CO3-catalyzed reaction of 2-oxindoles with enones with the assistance of atmospheric O2 via sequential Michael addition-oxidation-ring-cleavage process. The further intramolecular reaction leads to the formation of benzoazepinone, quinoline, and 3-oxindole derivatives.

Unexpected domino reaction via Pd-catalyzed Sonogashira coupling of benzimidoyl chlorides with 1,6-enynes and cyclization to synthesize quinoline derivatives

supporting information; experimental part, p. 1305 - 1308 (2010/04/26)

(Chemical Equation Presented) A domino reaction via palladium-catalyzed Sonogashira coupling of benzimidoyl chlorides with 1,6-enynes and then cyclization to form quinoline derivatives has been developed. The reaction conditions and the scope of the process are examined, and a plausible mechanism is proposed. The procedure is simple, rapid, and general, and the substrates are readily available. 2010 American Chemical Society.
