517-97-5 Usage
Description
This aporphine alkaloid occurs with sinomenine in Sinomenium acutum Rehd.
et Wils and was first isolated by Goto from the mother liquors following removal
of the former base. The alkaloid is crystalline, softens at 105°C and melts at
125°C. When crystallized from EtOH it has the higher melting point given above.
It is laevorotatory with [α]20D - 127.5° (EtOH) and is solu ble in most organic
solvents and dilute alkalies. The sparingly soluble hydrochloride has m.p. 286°C
(dec.); [α]14.5D - 148° (aqueous MeOH). A phenolic hydroxyl group and an
imino group are present and yield a series of derivatives, e.g. the N-methyl
methiodide, m.p. 224°C; N-acetyl derivative, m.p. 277°C; [α]18D - 395.24°
(MeOH-CHC13); O,N-diacetyl derivative, m.p. 170°C; [α]14D - 321.7° (MeOH);
G-methyl ether yielding the N-acetyl compound, m.p. 189°C and the O-ethyl
compound which forms a hydrochloride, m.p. 234-6°C; hydrobromide, m.p.
246-8°C and an ethiodide, m.p. l86-7°C. When degraded by the Hofmann
process, the alkaloid furnishes a trimethoxyvinylphenanthrene, m.p. 93-5°C.

Check Digit Verification of cas no
The CAS Registry Mumber 517-97-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 517-97:
(5*5)+(4*1)+(3*7)+(2*9)+(1*7)=75
75 % 10 = 5
So 517-97-5 is a valid CAS Registry Number.
