Check Digit Verification of cas no
The CAS Registry Mumber 99612-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,1 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99612-72:
(7*9)+(6*9)+(5*6)+(4*1)+(3*2)+(2*7)+(1*2)=173
173 % 10 = 3
So 99612-72-3 is a valid CAS Registry Number.

THE SYNTHESIS OF HELIOTRIDINE AND RELATED ALKALOIDS
Glinski, Jan A.,Zalkow, Leon H.
, p. 2857 - 2860 (2007/10/02)
An efficient synthesis of heliotridine from readily available retronecine was accomplished by nucleophilic displacement of the 7-mesylate, in the 7-mesyl-9-benzoate of retronecine with various cesium carboxylates in DMF, followed by hydrolysis.The synthet
