Check Digit Verification of cas no
The CAS Registry Mumber 155593-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,5,9 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 155593-19:
(8*1)+(7*5)+(6*5)+(5*5)+(4*9)+(3*3)+(2*1)+(1*9)=154
154 % 10 = 4
So 155593-19-4 is a valid CAS Registry Number.

Preparation and properties of chloro-3-methoxycatechols-components of pulp bleaching effluents
Smith, Terrence J.,Wearne, Ross H.,Wallis, Adrian F. A.
, p. 911 - 920 (2007/10/03)
The preparation and properties are given for the seven chlorinated 3-methoxycatechols, several of which have been reported as components of pulp bleaching effluents. The 4- and 6-substituted compounds and the trichloro-3-methoxycatechol were obtained by direct chlorination of the parent catechol or its diacetate. The 5-substituted compound was prepared by the known addition of hydrochloric acid to 3-methoxy-ortho-benzoquinone, and further chlorination gave the 4,5- and 5,6-dichloro isomers. The diacetates of all seven compounds were separated by gas chromatography. Electron impact mass spectra and 1H and 13C NMR data for the diacetates are given.
