Check Digit Verification of cas no

The CAS Registry Mumber 157129-55-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,2 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 157129-55:
(8*1)+(7*5)+(6*7)+(5*1)+(4*2)+(3*9)+(2*5)+(1*5)=140
140 % 10 = 0
So 157129-55-0 is a valid CAS Registry Number.

N-Hydroxymethylnorcotinine, a new primary in vitro metabolite of cotinine

Li,Gorrod

, p. 409 - 415 (1994)

1. N-Hydroxymethylnorcotinine; 5-(3'-pyridyl)-1-hydroxymethyl-pyrrolidone-2, was found as a new primary metabolite of cotinine in vitro. 2. N-Hydroxymethylnorcotinine was synthesized and characterized by gas chromatography-mass spectrometry, mass spectra, nuclear magnetic resonance and ultraviolet spectroscopy. 3. This new metabolite is formed by incubation of cotinine with hamster hepatic microsomes in the presence of NADPH and oxygen.
