826990-57-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 826990-57-2 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, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 826990-57:
(8*8)+(7*2)+(6*6)+(5*9)+(4*9)+(3*0)+(2*5)+(1*7)=212
212 % 10 = 2
So 826990-57-2 is a valid CAS Registry Number.

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.
