Check Digit Verification of cas no
The CAS Registry Mumber 99629-53-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,2 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99629-53:
(7*9)+(6*9)+(5*6)+(4*2)+(3*9)+(2*5)+(1*3)=195
195 % 10 = 5
So 99629-53-5 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
