1254343-12-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1254343-12-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,3,4 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1254343-12:
(9*1)+(8*2)+(7*5)+(6*4)+(5*3)+(4*4)+(3*3)+(2*1)+(1*2)=128
128 % 10 = 8
So 1254343-12-8 is a valid CAS Registry Number.

Catalytic enantioselective Friedlaender condensations: Facile access to quinolines with remote stereogenic centers
Li, Le,Seidel, Daniel
, p. 5064 - 5067 (2010)
Enamine catalysis enables the first catalytic enantioselective Friedlaender reaction. The desymmetrization of 4-substituted cyclohexanones upon reaction with o-aminobenzaldehydes allows for the synthesis of quinolines with remote stereogenic centers. Thes
