55870-50-3 Usage
Uses
Ammonium (-)-3-bromo-8-camphorsulfonate is bromocamphor solutions use in optically resolutions.
Purification Methods
Pass a hot aqueous solution of it through an alumina column to remove water-soluble coloured impurities which remain on the column when the ammonium salt is eluted with hot water. The salt is crystallised from water and dried over CaCl2 in a desiccator [Craddock & Jones J Am Chem Soc 84 1098 1962, Kauffmann J Prakt Chem 33 295 1966]. [Beilstein 11 H 319, 11 I 77, 11, II 183, 11 III 595.]
Check Digit Verification of cas no
The CAS Registry Mumber 55870-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,8,7 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 55870-50:
(7*5)+(6*5)+(5*8)+(4*7)+(3*0)+(2*5)+(1*0)=143
143 % 10 = 3
So 55870-50-3 is a valid CAS Registry Number.
