Check Digit Verification of cas no

The CAS Registry Mumber 1402730-50-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,7,3 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1402730-50:
(9*1)+(8*4)+(7*0)+(6*2)+(5*7)+(4*3)+(3*0)+(2*5)+(1*0)=110
110 % 10 = 0
So 1402730-50-0 is a valid CAS Registry Number.

Oxidative dearomative cross-dehydrogenative coupling of indoles with diverse C-H nucleophiles: Efficient Approach to 2,2-Disubstituted Indolin-3-ones

Jiang, Cheng-Shi,Liu, Xigong,Tang, Ying-De,Yan, Xue,Zhang, Hua

, (2020)

The oxidative, dearomative cross-dehydrogenative coupling of indoles with various C-H nucleophiles is developed. This process features a broad substrate scope with respect to both indoles and nucleophiles, affording structurally diverse 2,2-disubstituted indolin-3-ones in high yields (up to 99%). The oxidative dimerization and trimerization of indoles has also been demonstrated under the same conditions.

Indolyl substituted indole-3-ketone and synthesis method thereof

-

Paragraph 0066-0074, (2020/11/25)

The invention relates to an indolyl substituted indole-3-ketone and a synthesis method thereof. According to the method, an indole compound and an o-nitro alkyne compound are converted into the indolyl substituted indole-3-ketone in the argon atmosphere under a PPh3 reducing agent for the first time, and the prepared indole substituted indole-3-ketone is stable in molecular structure and excellentin chemical property. Reaction raw materials of the synthesis method are cheap and easy to obtain, and pretreatment is not needed; only acid and a reducing agent are used in the reaction without a metal catalyst so that raw materials are saved and the reaction cost is reduced; the whole reaction system is simple, reaction conditions are mild, reaction equipment is less, experimental operation issimple and convenient, and material sources are wide.
