Check Digit Verification of cas no

The CAS Registry Mumber 216393-57-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,3,9 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 216393-57:
(8*2)+(7*1)+(6*6)+(5*3)+(4*9)+(3*3)+(2*5)+(1*7)=136
136 % 10 = 6
So 216393-57-6 is a valid CAS Registry Number.

Beyond Directed ortho Metalation: Ruthenium-Catalyzed Amide-Directed CAr-OMe Activation/Cross-Coupling Reaction of Naphthamides with Aryl Boronates

Zhao, Yigang,Snieckus, Victor

supporting information, p. 4674 - 4677 (2015/10/12)

A new and general synthetic methodology for the construction of biaryl, heterobiaryl, and polyaryl molecules by the ruthenium-catalyzed cross-coupling of ortho-methoxy naphthamides with aryl boroneopentylates is described. The isomeric 1-MeO-2-naphthamides and 2-MeO-1-naphthamides furnish an expansive series of arylated naphthamides in excellent yields. Competition experiments showed the higher reactivity of 1-MeO-2-naphthamide over 2-MeO-benzamide. Orthogonality between the C-O activation/cross-coupling and the Suzuki-Miyaura reactions was established. The method provides naphthalenes which are difficult to prepare by directed ortho metalation.

C-H activation by amide chelation control: Ruthenium-catalyzed direct synthesis of 2-Aryl-3-furanamides

Zhao, Yigang,Snieckus, Victor

supporting information, p. 1527 - 1532 (2014/06/09)

A new, catalytic methodology for the synthesis of heterobiaryls by the ruthenium-catalyzed C-H activation/cross-coupling of heterocyclic amides with aryl boroneopentylates is surveyed. From this survey, the highly regioselective reaction of furan-3-carboxamide to give 2-aryl-3-furanamides is optimized and generalized in scope with respect to the aryl boroneopentylate coupling partners. Established thereby is a one-step synthetic method which may supercede the broadly applied two-step directed ortho metalation (DoM)-cross coupling reaction involving cryogenic and strong base conditions and which has potential for further ortho and remote metalation chemistry.

Beyond directed ortho metalation: Ruthenium-catalyzed amide-directed C Ar-N activation/C-C coupling reaction of anthranilamides with organoboronates

Zhao, Yigang,Snieckus, Victor

supporting information, p. 3200 - 3203 (2014/07/08)

A new, catalytic, and general methodology for the synthesis of biaryls and heterobiaryls by the cross coupling of anthranilamide derivatives (o-NMe 2 benzamides) with aryl boroneopentylates is described. The reaction proceeds under catalytic RuH2(CO)(PPh3)3 conditions driven by the activation of the unreactive C-N bond by amide directing group (DG)-Ru catalyst chelation. High regioselectivity, orthogonality with the Suzuki-Miyaura reaction, operational simplicity, and convenient scale-up are features of these reactions which may lend themselves to industrial applications.

Beyond directed ortho metalation: Ru-catalyzed CAr-O activation/cross-coupling reaction by amide chelation

Zhao, Yigang,Snieckus, Victor

supporting information, p. 11224 - 11227 (2014/09/29)

Disclosed is a new, catalytic, and general methodology for the chemical synthesis of biaryl, heterobiaryl, and polyaryl molecules by the cross-coupling of o-methoxybenzamides with aryl boroneopentylates. The reaction is based on the activation of the unreactive C-OMe bond by the proximate amide directing group using catalytic RuH2(CO)(PPh3)3 conditions. A one-step, base-free coupling process is thereby established that has the potential to supersede the useful two-step directed ortho metalation/cross- coupling reaction involving cryogenic temperature and strong base conditions. High regioselectivity, orthogonality with the Suzuki-Miyaura reaction, operational simplicity, minimum waste, and convenient scale-up make these reactions suitable for industrial applications.
