Check Digit Verification of cas no
The CAS Registry Mumber 90948-03-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,4 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90948-03:
(7*9)+(6*0)+(5*9)+(4*4)+(3*8)+(2*0)+(1*3)=151
151 % 10 = 1
So 90948-03-1 is a valid CAS Registry Number.

The metalation of 1- and 2-(trifluoromethyl)naphthalenes: Noteworthy site selectivities
Cottet, Fabrice,Castagnetti, Eva,Schlosser, Manfred
, p. 798 - 803 (2007/10/03)
This article provides insight into the various factors by which electronegative substituents affect the kinetic acidity of arenes and, more specifically, naphthalenes. Both 1- and 2-(trifluoromethyl)naphthalenes were consecutively treated with an organometallic or lithium dialkylamide-type base and carbon dioxide. Due to single electron-transfer triggered side reactions, the yields of (trifluoromethyl)naphthoic acids were moderate to poor. 1-(Trifluoromethyl)naphthalene was exclusively attacked at the 2-position as expected. The 2-isomer reacted with tert-butyllithium in the presence of potassium tert-butoxide solely at the 1-position, but with sec-butyllithium in the presence of N,N,N′,N′-tetramethylethylene-diamine concomitantly at the 3- and 4-positions. Authentic samples of the key acids 1, 4, 5 and 6 were prepared based on independent, unambiguous methods.
