1830-39-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1830-39-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,3 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1830-39:
(6*1)+(5*8)+(4*3)+(3*0)+(2*3)+(1*9)=73
73 % 10 = 3
So 1830-39-3 is a valid CAS Registry Number.

The Resolution and Absolute Configuration by X-Ray Crystallography of the Isomeric Octopamines and Synephrines

Midgley, John M.,Thonoor, Mohan C.,Drake, Alex F.,Williams, Clyde M.,Koziol, Anna E.,Palenik, Gus J.

, p. 963 - 970 (2007/10/02)

Racemates of the naturally occuring biogenic amines, o-, m-, and p-octopamine and p-synephrine, have been resolved by the preparation of suitable diastereomeric salts with antipodes of appropriate organic acids.The circular dichroism (c.d.) curves of (-)-m-octopamine hydrochloride and (-)-m-synephrine hydrochloride were superimposable and of opposite sign to those of the corresponding (-)-p-derivatives.X-ray crystallography of the (-)-3-bromocamphor-8-sulphonate salt of (-)-p-synephrine confirmed (for the first time by direct means in this series of compounds) that the absolute configuration of (-)-p-synephrine is R.It is concluded from the c.d. data that the absolute configuration of (-)-p-octopamine is also R.
