Check Digit Verification of cas no
The CAS Registry Mumber 5399-21-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,9 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5399-21:
(6*5)+(5*3)+(4*9)+(3*9)+(2*2)+(1*1)=113
113 % 10 = 3
So 5399-21-3 is a valid CAS Registry Number.

Catalytic enantioselective nazarov cyclization: Construction of vicinal all-carbon-atom quaternary stereocenters

The diastereoselective asymmetric synthesis of vicinal all-carbon-atom quaternary stereocenters is a challenging problem in organic synthesis for which only few solutions have been described. A catalytic asymmetric Nazarov cyclization of fully substituted dienones that provides cyclopentenone derivatives with vicinal quaternary stereocenters in high optical purity and as single diastereoisomers is now reported.
