Check Digit Verification of cas no
The CAS Registry Mumber 1185256-03-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,5,2,5 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1185256-03:
(9*1)+(8*1)+(7*8)+(6*5)+(5*2)+(4*5)+(3*6)+(2*0)+(1*3)=154
154 % 10 = 4
So 1185256-03-4 is a valid CAS Registry Number.

, p. 347 - 362 (2009)
All principal candesartan cilexetil impurities and/or degradation products were synthesized and identified. The differentiation of N-l and N-2 ethylated candesartan cilexetil derivatives was performed using ID and 2D NMR experiments. The influence of the magnetic field on the resolution and sensitivity of NMR experiments is shown. Selective hydrolysis of these compounds then provided corresponding producrs of hydrolysis of the ethoxy group. Institute of Organic Chemistry and Biochemistry.
