2842-13-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2842-13-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,4 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2842-13:
(6*2)+(5*8)+(4*4)+(3*2)+(2*1)+(1*3)=79
79 % 10 = 9
So 2842-13-9 is a valid CAS Registry Number.

Fluorescence sensing of Ag+ ions by desulfurization of an acetylthiourea derivative of 2-(2-hydroxyphenyl)benzothiazole

Hwang, Keum Saem,Park, Ka Young,Kim, Da Bin,Chang, Suk-Kyu

, p. 413 - 419 (2017)

A novel Ag+-selective reaction-based probe based on an acetylthiourea derivative of 2-(2-hydroxyphenyl)benzothiazole dye was investigated. The designed probe showed pronounced off-on type fluorescence signaling behavior towards Ag+ i

Solid-state Fluorescent Photophysics of Some 2-Substituted Benzothiazoles

Anthony, Kevin,Brown, Robert G.,Hepworth, John D.,Hodgson, Kevin W.,May, Bernadette,West, Michael A.

, p. 2111 - 2118 (2007/10/02)

The solid-state fluorescence properties of a series of benzothiazoles with phenyl, napthalene, and coumarin moieties substituted at the 2-position have been investigated.The necessity for a 2'-OH substituent for fluorescence has been confirmed and the effects of further substitution in the 2-phenyl ring are reported.
