Check Digit Verification of cas no
The CAS Registry Mumber 917252-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,2,5 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 917252-80:
(8*9)+(7*1)+(6*7)+(5*2)+(4*5)+(3*2)+(2*8)+(1*0)=173
173 % 10 = 3
So 917252-80-3 is a valid CAS Registry Number.

Major metabolites of Zolpidem: Expeditious synthesis and mass spectra

, p. 1318 - 1321 (2006)
An expeditious route to the two major metabolites of Zolpidem - and readily applicable to the synthesis of the drug - was established via a cyclization reaction between a 2-aminopyridine and a suitable α-bromoacetophenone. The structures of the target compounds were confirmed from a 2D 1H- 15N NMR correlation. Their mass spectra contribute to a reliable toxicological identification of the drug in the case of drug-facilitated crimes.
