82-55-3 Usage
Description
Present in several Iboga species, this base is slightly laevorotatory, having [α]D -
5° (CHC13 ). It contains one methoxyl group, an imino group and a secondary
hydroxyl group. It forms a crystalline p-toluenesulphonyl derivative, m.p. 267-
8°C. On catalytic reduction, the base furnishes ibogaine (q.v.). The structure has
been determined from chemical and spectroscopic evidence to be decarbomethoxyvoacangarine.

Check Digit Verification of cas no
The CAS Registry Mumber 82-55-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 82-55:
(4*8)+(3*2)+(2*5)+(1*5)=53
53 % 10 = 3
So 82-55-3 is a valid CAS Registry Number.
