25471-42-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25471-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,7 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 25471-42:
(7*2)+(6*5)+(5*4)+(4*7)+(3*1)+(2*4)+(1*2)=105
105 % 10 = 5
So 25471-42-5 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
