83201-12-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83201-12-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,0 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83201-12:
(7*8)+(6*3)+(5*2)+(4*0)+(3*1)+(2*1)+(1*2)=91
91 % 10 = 1
So 83201-12-1 is a valid CAS Registry Number.

Synthesis of Novel Hydroxyellipticines
Dharmasena, Priyanthi M.,Shannon, Patrick V. R.
, p. 7119 - 7122 (2007/10/02)
7-Methoxy-8-hydroxy and 10-hydroxyellipticines have been synthesised using pivaloyl esters for regioselective deactivation and steric protection of reactive ring-A positions; the final cyclisation sequence has been analysed by 1H-NMR.
