Check Digit Verification of cas no

The CAS Registry Mumber 1643935-92-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,3,9,3 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1643935-92:
(9*1)+(8*6)+(7*4)+(6*3)+(5*9)+(4*3)+(3*5)+(2*9)+(1*2)=195
195 % 10 = 5
So 1643935-92-5 is a valid CAS Registry Number.

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

Jolit, Anais,Walleser, Patrick M.,Yap, Glenn P. A.,Tius, Marcus A.

, p. 6180 - 6183 (2014/06/23)

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.
