Description
A bisbenzylisoquinoline type alkaloid present in Daphnandra Dielsii Perkins and
D. repandula, the original formula of C4oH460sN2 was altered to C37H3407N2
and finally to that given above. When purified by recrystallization from MeOH
it forms slender yellow needles which darken and shrink,at 180-5°C and then
decompose over the rather wide temperature range given above. The base is
dextrorotatory with [α]16D + 434° (c 0.2, MeOH) or [α]27D + 473° (c 0.98,
CHCI 3). A methoxyl group, a methylenedioxy group, two methylimino groups
and a double ether bridge are present. The dihydrochloride yields yellow prisms
from H20, decomposing at 100°C; the dioxalate, crystallizing from MeOH as
yellow tetrahedra, decomposes at 214° C and the dimethiodide, decomposes at
240° C. The structure has been established from the NMR and mass spectra.

Check Digit Verification of cas no
The CAS Registry Mumber 20398-02-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,9 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20398-02:
(7*2)+(6*0)+(5*3)+(4*9)+(3*8)+(2*0)+(1*2)=91
91 % 10 = 1
So 20398-02-1 is a valid CAS Registry Number.
