Check Digit Verification of cas no

The CAS Registry Mumber 119866-82-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,8,6 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 119866-82:
(8*1)+(7*1)+(6*9)+(5*8)+(4*6)+(3*6)+(2*8)+(1*2)=169
169 % 10 = 9
So 119866-82-9 is a valid CAS Registry Number.

Methyl 3,3,3-trifluoropyruvate hemiaminals: Stability and transaminations

Dolensky, Bohumil,Kví?ala, Jaroslav,Paleta, Old?ich

, p. 745 - 751 (2005)

Hemiaminals of methyl 3,3,3-trifluoropyruvate with aromatic amines, benzylic monoamines and diamines were prepared and their interconversions studied using NMR spectrometry. In solution, benzylic hemiaminals were found to be stable in contrast to aromatic hemiaminals, which, in turn, were stable in the solid state.

Preparation of new trifluoromethyl substituted Tri- and tetracyclic heterocycles with peganin skeleton from a methyl 3,3,3-trifluoropyruvate/2-aminobenzylamine adduct

Dolensky, Bohumil,Kvicala, Jaroslav,Paleta, Oldrich,Cejka, Jan,Ondracek, Jan

, p. 6939 - 6942 (2007/10/03)

Addition of 2-aminobenzylamino to methyl trifluoropyruvate afforded methyl 2-((2-aminobenzyl)amino)-3,3,3-trifluoro-2-hydroxypropionate, which reacted with various ketones to give new fluorinated tricyclic and tetracyclic heterocycles with the skeleton of
