1453-59-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1453-59-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,5 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1453-59:
(6*1)+(5*4)+(4*5)+(3*3)+(2*5)+(1*9)=74
74 % 10 = 4
So 1453-59-4 is a valid CAS Registry Number.

Metabolism of fentanyl and acetylfentanyl in human-induced pluripotent stem cell-derived hepatocytes

To evaluate the capability of human-induced pluripotent stem cell-derived hepatocytes (h-iPS-HEP) in drug metabolism, the profiles of the metabolites of fentanyl, a powerful synthetic opioid, and acetylfentanyl, an N-acetyl analog of fentanyl, in the cells were determined and analyzed. Commercially available h-iPSHEP were incubated with fentanyl or acetylfentanyl for 24 or 48 h. After enzymatic hydrolysis, the medium was deproteinized with acetonitrile, then analyzed by LC/MS. Desphenethylated metabolites and some hydroxylated metabolites, including 4′-hydroxy-fentanyl and β-hydroxy-fentanyl, were detected as metabolites of fentanyl and acetylfentanyl in the medium. The main metabolite of fentanyl with h-iPS-HEP was the desphenethylated metabolite, which was in agreement with in vivo results. These results suggest that h-iPSHEP may be useful as a tool for investigating drug metabolism.
