144298-10-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144298-10-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,9 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144298-10:
(8*1)+(7*4)+(6*4)+(5*2)+(4*9)+(3*8)+(2*1)+(1*0)=132
132 % 10 = 2
So 144298-10-2 is a valid CAS Registry Number.

A practical route to C-8 substituted fluoroquinolones
Carretero,Garcia Ruano,Vicioso
, p. 7373 - 7382 (2007/10/02)
The ortho metalation of N-(tert-butoxycarbonyl)-3,4-difluoroaniline, with t-BuLi at -78°C in THF occurred regioselectively at C-2 position. The resulting lithiated species reacted with a variety of electrophiles to give 2-substituted-3,4-difluoranilines i
