826990-64-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 826990-64-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,6,9,9 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 826990-64:
(8*8)+(7*2)+(6*6)+(5*9)+(4*9)+(3*0)+(2*6)+(1*4)=211
211 % 10 = 1
So 826990-64-1 is a valid CAS Registry Number.

Controllable Rh(III)-Catalyzed Annulation between Salicylaldehydes and Diazo Compounds: Divergent Synthesis of Chromones and Benzofurans

Sun, Peng,Gao, Shang,Yang, Chi,Guo, Songjin,Lin, Aijun,Yao, Hequan

, p. 6464 - 6467 (2016/12/23)

A Rh(III)-catalyzed annulation between salicylaldehydes and diazo compounds with controllable chemoselectivity is described. AgNTf2 favored benzofurans via a tandem C-H activation/decarbonylation/annulation process, while AcOH led to chromones through a C-H activation/annulation pathway. The reaction exhibited good functional group tolerance and scalability. Moreover, only a single regioisomer of benzofuran was obtained due to the in situ decarbonylation orientation effect.

CuI-catalyzed domino process to 2,3-disubstituted benzofurans from 1-bromo-2-iodobenzenes and β-keto esters

Lu, Biao,Wang, Bao,Zhang, Yihua,Ma, Dawei

, p. 5337 - 5341 (2008/02/07)

(Chemical Equation Presented) CuI-catalyzed coupling of 1-bromo-2-iodobenzenes with β-keto esters in THF at 100°C leads to 2,3-disubstituted benzofurans. This domino transformation involves an intermolecular C-C bond formation and a subsequent intramolecular C-O bond formation process. Benzofurans with different substituents at the 5- and 6-position are accessible by employing the corresponding 1-bromo-2-iodobenzenes.

One-pot synthesis of fluorine containing 3-cyano/ethoxycarbonyl-2-methyl- benzo[b]furans

RamaRao,Venkat Reddy,Maitraie,Ravikanth,Yadla,Narsaiah,Shanthan Rao

, p. 12231 - 12237 (2007/10/03)

Fluoro-substituted 3-cyano-2-methyl-benzo[b]furans and ethyl 2-methyl-benzo[b]furan-3-carboxylates are conveniently prepared in a single step in good yield by the microwave induced tandem intramolecular Wittig and Claisen rearrangement reactions of the corresponding [(aryloxyacetyl) (cyano) methylene] triphenylphosphorane and [(aryloxyacetyl) (ethoxycarbonyl) methylene] triphenylphosphoranes, respectively.
