Check Digit Verification of cas no

The CAS Registry Mumber 158817-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,8,1 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 158817-21:
(8*1)+(7*5)+(6*8)+(5*8)+(4*1)+(3*7)+(2*2)+(1*1)=161
161 % 10 = 1
So 158817-21-1 is a valid CAS Registry Number.

Photoredox/Nickel-Catalyzed Single-Electron Tsuji–Trost Reaction: Development and Mechanistic Insights

Matsui, Jennifer K.,Gutiérrez-Bonet, álvaro,Rotella, Madeline,Alam, Rauful,Gutierrez, Osvaldo,Molander, Gary A.

supporting information, p. 15847 - 15851 (2018/11/23)

A regioselective, nickel-catalyzed photoredox allylation of secondary, benzyl, and α-alkoxy radical precursors is disclosed. Through this manifold, a variety of linear allylic alcohols and allylated monosaccharides are accessible in high yields under mild reaction conditions. Quantum mechanical calculations [DFT and DLPNO-CCSD(T)] support the mechanistic hypothesis of a Ni0 to NiII oxidative addition pathway followed by radical addition and inner-sphere allylation.

Synthesis of the C1-C9 fragment of the potent antitumor agent dictyostatin

Dias, Luiz C.,Sant'ana, Danilo P.,Vieira, Ygor W.,Gonc?alves, Caroline C.S.,Lima, Dimas J.P.

, p. 344 - 348 (2012/06/01)

We describe herein a short and efficient synthesis of the C1-C9 fragment of the potent antitumor agent dictyostatin. Notable features of this approach include a Sharpless asymmetric epoxidation followed by epoxide opening under Myashita's conditions to in
