Check Digit Verification of cas no

The CAS Registry Mumber 1591916-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,1,9,1 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1591916-40:
(9*1)+(8*5)+(7*9)+(6*1)+(5*9)+(4*1)+(3*6)+(2*4)+(1*0)=193
193 % 10 = 3
So 1591916-40-3 is a valid CAS Registry Number.

Palladium-Catalyzed Allenamide Carbopalladation/Allylation with Active Methine Compounds

Zhu, Xiaoyi,Li, Ruibo,Yao, Hequan,Lin, Aijun

, p. 4630 - 4634 (2021/06/28)

A palladium-catalyzed allenamide carbopalladation/allylation with active methine compounds has been developed. Various indoles and isoquinolinones bearing a quaternary carbon center were achieved with good efficiency, a broad substrate scope and good functional group tolerance. This reaction underwent cascade oxidative addition, carbopalladation, and allylic alkylation, and two new C-C bonds were formed in one pot.

Asymmetric Domino Heck/Dearomatization Reaction of β-Naphthols to Construct Indole-Terpenoid Frameworks

Wang, Dong-Chao,Cheng, Peng-Peng,Yang, Ting-Ting,Wu, Pan-Pan,Qu, Gui-Rong,Guo, Hai-Ming

supporting information, p. 7865 - 7872 (2021/10/20)

A palladium-catalyzed enantioselective Heck cyclization/dearomatization cascade via capturing the cyclized Heck π-allylpalladium intermediate by β-naphthols is reported, which provides a new strategy for the construction of chiral indole-terpenoid framewo
