6582-68-9 Usage
Description
An imidazolidinocarbazole alkaloid, this base occurs in Aspidosperma duckei
Hub. and also in A. macrocarpon Mart. It may be purified by recrystallization
from either MeOH or CHC1 3 when it forms colourless needles. It has [α]27D +
16.7° (c 0.6, CHC13 ). The ultraviolet spectrum in ethanol solution has absorp-tion maxima at 246 and 297 mil. In 5N/HCl the absorption maxima occur at
262 and 268.5 mil with shoulders at 249 and 255 mil. The alkaloid contains one
hydroxyl group and on acetylation yields the O-acetate, m.p. 202-5°C; [α]26D +
37° (c 2.97, CHCI3 ).

Check Digit Verification of cas no
The CAS Registry Mumber 6582-68-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,8 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6582-68:
(6*6)+(5*5)+(4*8)+(3*2)+(2*6)+(1*8)=119
119 % 10 = 9
So 6582-68-9 is a valid CAS Registry Number.
