Check Digit Verification of cas no

The CAS Registry Mumber 35856-81-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,8,5 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 35856-81:
(7*3)+(6*5)+(5*8)+(4*5)+(3*6)+(2*8)+(1*1)=146
146 % 10 = 6
So 35856-81-6 is a valid CAS Registry Number.

Observation of Stable and Transient Intermediates in Palladium Complex-catalysed Cross-coupling Reactions

Brown, John M.,Cooley, Neil A.

, p. 1345 - 1347 (1988)

Complexes of 1,1'-bis(diphenylphosphino)ferrocene corresponding to the separate steps of cross-coupling have been identified and related to the catalytic cycle.

Visible-Light-Promoted Cross-Coupling of N-Alkylpyridinium Salts and Nitrostyrenes

Ferko, Branislav,Mar?eková, Michaela,Detková, Katarína Ráchel,Doháňo?ová, Jana,Berke?, Du?an,Jakubec, Pavol

supporting information, p. 8705 - 8710 (2021/11/20)

A stereoselective, denitrative cross-coupling of β-nitrostyrenes with N-alkylpyridinium salts for the preparation of functionalized styrenes has been developed. The visible-light-induced reaction proceeds without any catalyst at ambient temperature. Broad in scope and tolerant to multiple functional groups, the moderately yielding transformation is orthogonal to several traditional metal-catalyzed cross-couplings.

Palladium-catalyzed reaction of γ-silylated allyl acetates proceeding through 1,2-shift of a substituent on silicon

Horino, Yoshikazu,Ishibashi, Mayo,Nakasai, Kosuke,Korenaga, Toshinobu

, (2020/08/28)

The palladium-catalyzed reaction of γ-silylated allyl acetates with water in the presence of CsF induces a previously unprecedented 1,2-shift of a substituent on silicon to produce allylsilanes in situ. The catalytic activity of the palladium increased when using an electron-poor phosphine ligand possessing fluorinated substituents. Further investigation of the reaction revealed that the approximate order of the migratory aptitude of groups from silicon was PhC≡C, allyl > Bn > Ph, vinyl > alkyl (Me, Et). A density functional theory study was employed to explore the reaction mechanism. Finally, the Hosomi–Sakurai-type allylation of aldehydes with in situ-generated α,γ-disubstituted allylsilanes was also investigated.
