2134-83-0 Usage
Description
A further alkaloid occurring in Voacanga africana, the base forms cubic crystals from MeOH and is strongly laevorotatory with [α]23D- 158.5° (c 1.0, CHCI3) or
- 148.3° (c 1.0, MeOH). The ultraviolet spectrum has two absorption maxima at
239 and 315 mμ. The alkaloid forms a hydrochloride as prismatic plates from
MeOH, m.p. 245-8°C (dec.); [α]22D - 120.1° (c 1.0, MeOH); the methiodide,
m.p. 212-4°C (dec.); [α]23D - 117.2° (c 1.0, MeOH) and the 2:4-dinitrophenylhydrazone
as deep red crystals, m.p. 172-5°C.
Definition
ChEBI: An indole alkaloid that is vobasan in which the bridgehead methyl group is substituted by a methoxycarbonyl group and an additional oxo substituent is present in the 3-position.

Check Digit Verification of cas no
The CAS Registry Mumber 2134-83-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,3 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2134-83:
(6*2)+(5*1)+(4*3)+(3*4)+(2*8)+(1*3)=60
60 % 10 = 0
So 2134-83-0 is a valid CAS Registry Number.
