7336-40-5 Usage
Description
A colchicine type alkaloid, N-acetyldemecolcine occurs in both the corms and
seeds of Colchicum autumnale, Gloriosa virescens and Littoria modesta. It is
separated from the numerous other accompanying bases by column and thin_x0002_layer chromatography. The base is laevorotatory with a specific rotation of [α]D
- 2440 (c 1.0, CHC13).
Check Digit Verification of cas no
The CAS Registry Mumber 7336-40-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,3 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7336-40:
(6*7)+(5*3)+(4*3)+(3*6)+(2*4)+(1*0)=95
95 % 10 = 5
So 7336-40-5 is a valid CAS Registry Number.

The latter part of the natural pathway to colchicine is known to involve conversion of phenethyltetrahydroisoquinoline (2) by phenol oxidation into a dienone (O-methylandrocymbine) (4), the dienone subsequently undergoing ring-expansion to generate the tr
