Check Digit Verification of cas no
The CAS Registry Mumber 6737-68-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,3 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6737-68:
(6*6)+(5*7)+(4*3)+(3*7)+(2*6)+(1*8)=124
124 % 10 = 4
So 6737-68-4 is a valid CAS Registry Number.

Comparative synthetic study of 1,4-dihydroxy anthraquinone (quinizarin) dye intermediate
Bhatti, Khalid Pervez,Zuber, Muhammad
, p. 758 - 763 (2012/07/28)
1,4-Dihydroxy anthraquinone (quinizarin) has been synthesised with two different precursors' p-chlorophenol and hydroquinone by condensation of phthalic anhydride. It has been noticed that p-chlorophenol gave higher yield as compared to hydroquinone on reaction with phthalic anhydride at 200°C within 3:30 hours in a mixture of concentrated H2SO4 and boric acid. Three disperse dyes have been prepared from the quinizarin. The physical properties of three different colored dyes have also been discussed.
