Check Digit Verification of cas no

The CAS Registry Mumber 5102-83-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,0 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5102-83:
(6*5)+(5*1)+(4*0)+(3*2)+(2*8)+(1*3)=60
60 % 10 = 0
So 5102-83-0 is a valid CAS Registry Number.

A quantitative one-pot synthesis method for industrial azo pigments with recyclable wastewater

Feng, Guangyuan,Zhu, Meiling,Liu, Lei,Li, Chunbao

supporting information, p. 1769 - 1776 (2019/04/08)

Most industrial azo pigments are synthesized by diazotization in one pot and then coupling in another. This two-pot process has been transformed into a one-pot method by adding granular PTFE (polytetrafluoroethylene) to a mechanically agitated aqueous mixture of NaNO2, HCl, a diazo component and a coupling component. This method avoids the step of using a base or a surfactant to dissolve the coupling component. The reactions were fast and quantitative. The granular PTFE, wastewater and excess HCl were then reused 11 times without deteriorating the reaction rate and product purity. Altogether, 22 industrial pigments and 3 azo compounds were synthesized and the reaction can produce up to 22.7 g of product in the laboratory. Some reactions require less than 2 equiv. of HCl and a mechanism explaining this is proposed. In addition, an o-nitro group effect is advanced to explain the differences in coupling reaction rates for o-, m- and p-nitroaniline.
