20452-82-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20452-82-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,5 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20452-82:
(7*2)+(6*0)+(5*4)+(4*5)+(3*2)+(2*8)+(1*2)=78
78 % 10 = 8
So 20452-82-8 is a valid CAS Registry Number.

Szeto, Judy,Lemoine, Remy,Nguyen, Rosary,Olson, Lori L.,Tanga, Mary J.
, p. 391 - 394 (2018)
[15N]-Cholamine is an isotope tag for metabolomics research, because it possesses 2 important properties: an NMR active isotope and a permanent charge for MS sensitivity. Here, we present a scalable synthesis of [15N]-cholamine.
