117657-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117657-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,5 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 117657-48:
(8*1)+(7*1)+(6*7)+(5*6)+(4*5)+(3*7)+(2*4)+(1*8)=144
144 % 10 = 4
So 117657-48-4 is a valid CAS Registry Number.

THE SYNTHESIS OF NEOPHYLLITHIUM AND ITS REACTION WITH ANTHRACENE
Zieger, Herman,Perri, Carolyn,Bharucha, Kamal
, p. 5989 - 5992 (2007/10/02)
The transmetalation reaction between t-butyllithium and dineophylmercury produces pure neophyllithium, 1, in a rapid, convenient manner as shown by FT-NMR.Alkylation of anthracene with 1 in HMPA gives 6-10percent yields of unrearranged adduct.
