Check Digit Verification of cas no

The CAS Registry Mumber 1204751-39-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,7,5 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1204751-39:
(9*1)+(8*2)+(7*0)+(6*4)+(5*7)+(4*5)+(3*1)+(2*3)+(1*9)=122
122 % 10 = 2
So 1204751-39-2 is a valid CAS Registry Number.

Enamine-lminium ion nazarov cyclization of α-ketoenones

Bow, William F.,Basak, Ashok K.,Jolit, Anais,Vicic, David A.,Tius, Marcus A.

, p. 440 - 443 (2010)

[Chemical equaction presented] The mono-triflate salts of some chiral nonracemic 1,2-diamines react with α-ketoenones in a stoichiometric reaction to form products of the Nazarov cyclization in high enantiomeric ratios. The mechanism appears to involve rearrangement of an enamine-iminium ion.
