134949-03-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134949-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,4 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 134949-03:
(8*1)+(7*3)+(6*4)+(5*9)+(4*4)+(3*9)+(2*0)+(1*3)=144
144 % 10 = 4
So 134949-03-4 is a valid CAS Registry Number.

1H and 13C NMR Spectra of Fifteen Substituted Isoquinolines
Nelson, Janis T.,Davis, Roman
, p. 513 - 517 (1991)
Detailed analyses of the 1H and 13C NMR spectra of fifteen momo- and di-substituted isoquinoline derivatives were carried out by two-dimensional 1H-1H and 1H-13C shift correlation and nuclear Overhauser effect difference techniques.
