5610-39-9 Usage
Description
A complex alkaloid occurring in Alangium lamarckii Thw., the base yields
colourless crystals from EtOH and is laevorotatory with [α]25D - 84° (c 1.0,
pyridine). The ultraviolet spectrum has been fully determined. In MeOH it shows
a single broad absorption maximum at 279 mJl. In 0.1 N/HC1 there is a very
small hypsochromic shift to 277 mJl while in 0.1 N/NaOH, there are two absorp_x0002_tion maxima at 279 and 319 mμ. Two methoxyl groups, two imino groups and
one hydroxyl group are present. The latter furnishes the O-methy1 ether, m.p.
163°C;[α]20D - 18.8° (MeOH). The above structure has been confirmed by
synthesis.

Check Digit Verification of cas no
The CAS Registry Mumber 5610-39-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,1 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5610-39:
(6*5)+(5*6)+(4*1)+(3*0)+(2*3)+(1*9)=79
79 % 10 = 9
So 5610-39-9 is a valid CAS Registry Number.
