176722-51-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 176722-51-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,7,2 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 176722-51:
(8*1)+(7*7)+(6*6)+(5*7)+(4*2)+(3*2)+(2*5)+(1*1)=153
153 % 10 = 3
So 176722-51-3 is a valid CAS Registry Number.

2-(trifluoromethyl)quinolines from anilines: A novel mode of isomerization and cyclization
Keller,Schlosser
, p. 4637 - 4644 (2007/10/03)
Deprotonation of N-ethylidene-tert-butylamine with lithium diisopropylamide and subsequent condensation with ethyl trifluoroacetate gives 4-tert-butylamino-1,1,1-trifluorobut-3-en-2-one. An exchange of the amino substituent occurs when the latter compound
