Description
Hodgkins and his co-workers have isolated this alkaloid from Coryphantha macromeris (Engelm.) Lem. Britton and Rose (Syn. Thelocactus macromeris (Engelm.) L. Benson and it has subsequently been discovered in C. runyonii. It is a laevorotatory base with [α]25D - 42.61° (c 2.0, EtOH) or - 147.01° (c 3.9, CHC13). The synthetic (±)-form has a higher m.p. l46-7°C and yields a crystalline picrate, m.p. 147°C. Spectroscopic and chemical data are in accord with the structure (-)- -(3 :4-dimethoxyphenyl)- -(dimethylamino)ethanol.References

The CAS Registry Mumber 19751-75-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,5 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.Calculate Digit Verification of CAS Registry Number 19751-75:
(7*1)+(6*9)+(5*7)+(4*5)+(3*1)+(2*7)+(1*5)=138
138 % 10 = 8
So 19751-75-8 is a valid CAS Registry Number.
