548-11-8 Usage
Description
First isolated from Lycoris radiata, this alkaloid has since been found in several
species of Narcissus. It is strongly laevorotatory with [α]D - 170.5° (c 0.18,
EtOH) or - 151 ° (c 0.42, CHCI3). The ultraviolet spectrum consists of a single
absorption maximum at 282 mJI. The salts and derivatives crystallize readily and
include the hydriodide, m.p. 237°C (dec.); the perchlorate, m.p. 260°C (dec.),
the methiodide, m.p. 259-261°C (dec.); [α]29D~l - 129° (c 0.39, H20); the methoperchlorate, m.p. 239-241°C and the O-acetate, m.p. 184°C. Two methoxyl
groups and a non-phenolic hydroxyl group are present.

Check Digit Verification of cas no
The CAS Registry Mumber 548-11-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 548-11:
(5*5)+(4*4)+(3*8)+(2*1)+(1*1)=68
68 % 10 = 8
So 548-11-8 is a valid CAS Registry Number.
