Check Digit Verification of cas no

The CAS Registry Mumber 72328-02-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,3,2 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 72328-02:
(7*7)+(6*2)+(5*3)+(4*2)+(3*8)+(2*0)+(1*2)=110
110 % 10 = 0
So 72328-02-0 is a valid CAS Registry Number.

Studies on the Formation of Benzanthrones in Alkaline Anthraquinone Pulping

Karhunen, Pirkko,Brunow, Goesta

, p. 945 - 948 (2007/10/02)

Loss of anthraquinone (AQ) in alkaline pulping is partly attributed to irreversible reactions of AQ or AQ-derived compounds with lignin fragments. 3-(4-Hydroxy-3-methoxyphenyl)benzanthracen-7-one, 3-(4-hydroxy-3,5-diemethoxyphenyl)benzanthracen-7-one and 3-(4-hydroxyphenyl)benzanthracen-7-one have been synthesized and their formation in reactions of isolated lignins has been studied. 2-(4-Hydroxy-3-methoxyphenyl)anthracene-9,10-dione (2-vanillylanthraquinone) has also been prepared.
