Check Digit Verification of cas no
The CAS Registry Mumber 121633-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,3 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121633-50:
(8*1)+(7*2)+(6*1)+(5*6)+(4*3)+(3*3)+(2*5)+(1*0)=89
89 % 10 = 9
So 121633-50-9 is a valid CAS Registry Number.

Synthesis and spectroscopic study of 13C-labelled citric acids
Winkel, C.,Buitenhuis, E. G.,Lugtenburg, J.
, p. 51 - 56 (2007/10/02)
The synthesis of (1'-13C)-, (3-13C)- and (2,4-13C2)citric acid from simple starting compounds is described.Using the same procedure, any mono- or multiply-labelled citric acid can be prepared.The 13C-labelled citric acids have been characterized by 1H NMR, 13C NMR and mass spectroscopy.
