773137-52-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 773137-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,3,1,3 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 773137-52:
(8*7)+(7*7)+(6*3)+(5*1)+(4*3)+(3*7)+(2*5)+(1*2)=173
173 % 10 = 3
So 773137-52-3 is a valid CAS Registry Number.

A convenient and general method for the synthesis of indole-2,3- dicarboxylates and 2-arylindole-3-carboxylates

Sayyed, Iliyas Ali,Alex, Karolin,Tillack, Annegret,Schwarz, Nicolle,Michalik, Dirk,Beller, Matthias

, p. 4525 - 4528 (2007)

A transition-metal-free, simple and efficient one-pot method for the synthesis of indole-2,3-dicarboxylates and 2-aryl-indole-3-carboxylates is described. The corresponding products are obtained by a domino hydroamination/Fischer indole cyclization in goo

C-H Activation-Based Traceless Synthesis via Electrophilic Removal of a Directing Group. Rhodium(III)-Catalyzed Entry into Indoles from N-Nitroso and α-Diazo-β-keto Compounds

Wang, Jie,Wang, Mingyang,Chen, Kehao,Zha, Shanke,Song, Chao,Zhu, Jin

, p. 1178 - 1181 (2016/03/15)

A distinct C-H activation-based traceless synthetic protocol via electrophilic removal of a directing group is reported, complementing the currently exclusively used nucleophilic strategy. Rh(III)-catalyzed, N-nitroso-directed C-H activation allows the development of a traceless, atom- and step-economic, cascade approach for the synthesis of indole skeletons, starting from readily available N-nitroso and α-diazo-β-keto compounds. Importantly, the cyclization/denitrosation reaction represents a hitherto unobserved reactivity pattern for the N-nitroso group.
