Check Digit Verification of cas no

The CAS Registry Mumber 132902-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,0 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 132902-45:
(8*1)+(7*3)+(6*2)+(5*9)+(4*0)+(3*2)+(2*4)+(1*5)=105
105 % 10 = 5
So 132902-45-5 is a valid CAS Registry Number.

ASYMMETRIC SYNTHESIS OF FURANONES

Desmaele, Didier,Angelo, Jean, d',Bois, Claudette

, p. 759 - 762 (1990)

Addition of imine 10 to methyl acrylate led exclusively, after hydrolytic work-up, to furanone 11 (95percent stereoselectivity).By contrast, addition of this imine to MVK was not regioselective, giving a mixture of compounds 18, 19 and 20.

New Approach to Chiral 5,5-Disubstituted Tetronic Acids. Enantioselective Synthesis of (-)-Vertinolide.

Desmaele, Didier

, p. 2925 - 2934 (1992)

A general protocol for enantioselective construction of tetronic acids bearing a stereogenic center at C-5 is described.The readily available Michael adduct 12, obtained by addition of methyl acrylate to imine 10 derived from 2-methyl-4,5-dihydrofuran-3-o
