Check Digit Verification of cas no

The CAS Registry Mumber 15757-31-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,5 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15757-31:
(7*1)+(6*5)+(5*7)+(4*5)+(3*7)+(2*3)+(1*1)=120
120 % 10 = 0
So 15757-31-0 is a valid CAS Registry Number.

Organocatalytic stereoselective conjugate addition of 3-substituted oxindoles with in situ generated ortho-quinone methides

Liang, Weihong,Yin, Wenhao,Wang, Tingzhong,Qiu, Fayang G.,Zhao, Junling

supporting information, p. 1742 - 1747 (2018/04/02)

A novel method for the stereoselective conjugate addition of 3-substituted oxindoles to in situ generated o-QMs was described. This process was catalyzed efficiently by a cinchonidine-derived squaramide catalyst in oil-water phase, furnishing the corresponding 3,3-disubsituted oxindole derivatives in moderate to high yields (up to 98%) with high stereoselectivities (up to 95% ee, 15.4:1 dr). The utility of this reaction was also investigated by the gram-scale synthesis and derivatization of one of the products.

Bifunctional tertiary amine-squaramide catalyzed asymmetric catalytic 1,6-conjugate addition/aromatization of para-quinone methides with oxindoles

Deng, Yu-Hua,Zhang, Xiang-Zhi,Yu, Ke-Yin,Yan, Xu,Du, Ji-Yuan,Huang, Hanmin,Fan, Chun-An

supporting information, p. 4183 - 4186 (2016/03/19)

The asymmetric catalytic 1,6-addition of p-QMs with racemic oxindoles under the bifunctional catalysis of C2-symmetric dimeric Cinchona-derived squaramide is described. This tertiary amine-squaramide catalyzed reaction provides a diastereoselective and enantioselective approach to the effective assembly of diverse diarylmethine-substituted oxindoles having vicinal tertiary and quaternary stereocenters.

Palladium-catalyzed asymmetric allylic alkylation of 3-aryloxindoles with allylidene dipivalate: A useful enol pivalate product

Trost, Barry M.,Masters, James T.,Burns, Aaron C.

supporting information, p. 2260 - 2264 (2013/03/28)

Triple A: The catalytic asymmetric allylic alkylation (AAA) of 3-aryloxindoles with allylidene dipivalate is described. This reaction affords stable, synthetically useful enol pivalates in high yield and with excellent regio- and enantioselectivity. A broad range of substrates is tolerated, including unprotected and 3-heteroaryl nucleophiles. Copyright
