6870-67-3 Usage
Description
This alkaloid of the pyrrolizidine group of bases occurs in Senecio cineraria D.C.,
S. crucifolia and S. Jacobea. It is a laevorotatory base with [α]17D - 46.3°
(CHCl 3 ). The alkaloid forms crystalline salts and derivatives, e.g. the hydrochloride, m.p. 220°C; [α]19D - 14.3° (H20); nitrate, m.p. 234°C; methiodide,
m.p. 255°C and the picrate, m.p. 180°C which is soluble in H20. The alkaloid
contains two active hydrogens and on alkaline hydrolysis yields retronecine and
jaconecic acid, ClOH16 0 6, m.p. 182°C; [α]25D + 31.7° containing three O-methyl
groups
Uses
Jacobine is a pyrrolizidine alkaloid which has been shown to be an herbivore insect deterrent and may be used in the protection of vegetation. Extracted from Crassocephalum plant of West Africa.

Check Digit Verification of cas no
The CAS Registry Mumber 6870-67-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,7 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6870-67:
(6*6)+(5*8)+(4*7)+(3*0)+(2*6)+(1*7)=123
123 % 10 = 3
So 6870-67-3 is a valid CAS Registry Number.
