Check Digit Verification of cas no

The CAS Registry Mumber 1538556-41-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,3,8,5,5 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1538556-41:
(9*1)+(8*5)+(7*3)+(6*8)+(5*5)+(4*5)+(3*6)+(2*4)+(1*1)=190
190 % 10 = 0
So 1538556-41-0 is a valid CAS Registry Number.

Synthesis of [13C6]-labelled phenethylamine derivatives for drug quantification in biological samples

Karlsen, Morten,Liu, Huiling,Berg, Thomas,Johansen, Jon Eigill,Hoff, Bard Helge

, p. 378 - 387 (2014/06/10)

The availability of high-quality 13C-labelled internal standards will improve accurate quantification of narcotics and drugs in biological samples. Thus, the synthesis of 10 [13C6]-labelled phenethylamine derivatives, namely amphetamine, methamphetamine, 3,4-methylenedioxyamphetamine, 3,4-methylenedioxymethamphetamine, 3,4-methylenedioxy-N-ethylamphetamine, 4-methoxyamphetamine, 4-methoxymethamphetamine, 3,5-dimethoxyphenethylamine 4-bromo-2,5- dimethoxyphenethylamine and 2,5-dimethoxy-4-iodophenethylamine, have been undertaken. [13C6]-Phenol proved to be an excellent starting material for making 13C-labelled narcotic substances in the phenethylamine class, and a developed Stille-type coupling enabled an efficient synthesis of the 3,4-methylenedioxy and 4-methoxy derivatives. The pros and cons of alternative routes and transformations are also discussed. The [ 13C6]-labelled compounds are intended for use as internal standards in forensic analysis, health sciences and metabolomics studies by gas chromatography-mass spectrometry and liquid chromatography-tandem mass spectrometry.
