1433-08-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1433-08-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,3 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1433-08:
(6*1)+(5*4)+(4*3)+(3*3)+(2*0)+(1*8)=55
55 % 10 = 5
So 1433-08-5 is a valid CAS Registry Number.

Syntheses of pterocarpenes and coumestans via regioselective cyclodehydration

Nayak, Maloy,Jung, Youngeun,Kim, Ikyon

, p. 8074 - 8087 (2016/09/09)

A highly efficient synthetic route to pterocarpenes and coumestans is described. BCl3-mediated dehydrative cyclization of 1,3-diaryloxyacetones under mild conditions permitted regioselective ring closure to afford 3-((2-iodoaryloxy)methyl)benzo

6-endo heck cyclization of 3-(2-iodophenoxy)methylbenzofurans: A useful approach to pterocarpenes

Fowler, Katherine J.,Ellis, Jillian L.,Morrow, Gary W.

, p. 1676 - 1682 (2013/05/21)

Mitsunobu coupling of 3-hydroxymethylbenzofurans with o-iodophenols affords 3-(2-iodophenoxy)methylbenzofurans which under go a useful 6-endo Heck cyclization under Jeffery conditions to afford pterocarpene-type heterocycles. The unsubstituted parent pterocarpene thus prepared was readily converted to coumestan via subsequent PCC oxidation. Supplemental materials are available for this article.

Smooth Conversion of 3,4-Diarylcoumarins and 3,4,5-Triaryl-2(5H)-furanones to 2H-Chromene and 2,5-Dihydrofuran Derivatives with Dimethyl Sulfide-Borane Complex

Verma, Parul,Singh, Sangeeta,Dikshit, D. K.,Ray, Suprabhat

, p. 68 - 70 (2007/10/02)

Reaction of 3,4-diarylcoumarins (3,4-diaryl-2-oxo-2H-1-benzopyrans) and 3,4,5-triaryl-2(5H)-furanones with dimethyl sulfide-borane complex affords the corresponding 2H-chromenes (2H-1-benzopyrans) and 2,5-dihydrofurans in high yields. 3,4-Diaryl-2(5H)-fur
