Description
This alkaloid has been isolated from the roots of Thalictrum dasycarpum Fisch. et al. It crystallizes as colourless rods from Et20 or needles from EtOH. It has a specific rotation of[α]25D - 210° (c 0.21, CHCI3) and gives an ultraviolet spectrum in EtOH with a single absorption maximum at 289 nm. The methyl ether forms needles from Et20-EtOH with m.p. 91-2°C. The structure has been proved by total synthesis of the base.References

The CAS Registry Mumber 18927-72-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,2 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.Calculate Digit Verification of CAS Registry Number 18927-72:
(7*1)+(6*8)+(5*9)+(4*2)+(3*7)+(2*7)+(1*2)=145
145 % 10 = 5
So 18927-72-5 is a valid CAS Registry Number.
