114263-43-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 114263-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,2,6 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 114263-43:
(8*1)+(7*1)+(6*4)+(5*2)+(4*6)+(3*3)+(2*4)+(1*3)=93
93 % 10 = 3
So 114263-43-3 is a valid CAS Registry Number.

REINVESTIGATION OF THE SUBSTITUTION PRODUCTS OF 8-AZATHEOPHYLLINE
L'abbe, Gerrit,Persoons, Marie-Anne,Toppet, Suzanne
, p. 659 - 662 (2007/10/02)
The structure of the substitution products of 8-azatheophylline can be elucidated easily by an inspection of the C-3a and C-7a absorptions in the 13C NMR spectra.On the basis of this criterion a number of published structures are revised.
