Check Digit Verification of cas no

The CAS Registry Mumber 22082-95-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,0,8 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22082-95:
(7*2)+(6*2)+(5*0)+(4*8)+(3*2)+(2*9)+(1*5)=87
87 % 10 = 7
So 22082-95-7 is a valid CAS Registry Number.

Nickel-catalyzed cross-coupling of aryl methyl ethers with aryl boronic esters

Tobisu, Mamoru,Shimasaki, Toshiaki,Chatani, Naoto

, p. 4866 - 4869 (2008)

(Chemical Equation Presented) To C-OMe and go: The title reaction, involving cleavage of a C-OMe bond, is demonstrated for the coupling of aryl methyl ethers on fused aromatic systems, such as naphthalene and phenanthrene, as well as anisoles containing electron-withdrawing groups with a wide range of boronic esters. cod=cycloocta-1,5-diene, Cy=cyclohexyl.

Tetraethylphosphorodiamidate-Directed Metalation Group: Directed Ortho and Remote Metalation, Cross Coupling, and Remote Phospha Anionic Fries Rearrangement Reactions

Alessi, Manlio,Blackburn, Thomas,Patel, Jignesh J.,Sawinski, Hannah,Snieckus, Victor

, (2020/05/18)

The linked directed ortho and remote metalation (DoM and DreM) and cross-coupling reactions of aryl phosphorodiamidates (Ar-OP(O)(NEt2)2) is reported. The o-iodo and o-boronato aryl tetraethylphosphorodiamidates 3, prepared by DoM, undergo orthogonal Ni- and Pd-catalyzed Suzuki-Miyaura cross coupling to furnish biaryls 4 and 5 in good to excellent yields. Silicon group protection of biaryl 4 via DoM followed by previously unobserved DreM phospha anionic Fries rearrangement affords biaryls 11 which, under acidic conditions, furnish oxaphosphorine oxides 12.

Rapid nickel-catalyzed suzuki-miyaura cross-couplings of aryl carbamates and sulfamates utilizing microwave heating

Baghbanzadeh, Mostafa,Pilger, Christian,Kappe, C. Oliver

supporting information; experimental part, p. 1507 - 1510 (2011/04/26)

High-speed and scalable nickel-catalyzed cross-coupling of arylboronic acids with aryl carbamates and sulfamates is achieved by using sealed-vessel microwave processing.(Figure Presented)
