Description
This alkaloid from Papaver orientale forms colourless crystals from AcOEt and
has [α] 22
D- 254° ± 4° (c 0.31, MeOH). It forms a methiodide, m.p. 252-3°C, a
methine, m.p. 195-7°C and dimethine, m.p. l46-8°C. Exhaustive methylation
gives trimethylamine and a nitrogen-free oil as the final products. Oxidation of
the alkaloid with chromic acid or KMn04 yields Alkaloid PO-4 (q.v.). When
refluxed with 5 per cent H2S04 the base yields formaldehyde which may arise
from either the hydrolysis of the methylenedioxy group or, more probably, that
of the 1: 3-benzodioxan group.

Check Digit Verification of cas no
The CAS Registry Mumber 23943-90-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,4 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 23943-90:
(7*2)+(6*3)+(5*9)+(4*4)+(3*3)+(2*9)+(1*0)=120
120 % 10 = 0
So 23943-90-0 is a valid CAS Registry Number.

SYNTHESIS OF ALKALOIDS USING REISSERT COMPOUNDS, IV. A NEW SYNTHESIS OF (+/-)-MECAMBRIDINE
Kerekes, P.
, p. 303 - 308 (2007/10/02)
A new multistep synthesis of (+/-)-mecambridine (9) has been achieved starting from 2-benzoyl-1-1,2-dihydro-8-methoxy-6,7-methylenedioxyisoquinoline (1) (Reissert compound) and 3-benzyloxy-4-methoxybenzyl chloride (2).The last two steps of this synthesis
