Check Digit Verification of cas no
The CAS Registry Mumber 7559-72-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,5 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7559-72:
(6*7)+(5*5)+(4*5)+(3*9)+(2*7)+(1*2)=130
130 % 10 = 0
So 7559-72-0 is a valid CAS Registry Number.

Page/Page column 7, (2009/06/27)
An improved process for the manufacture of a polyphenol compound such as bisphenol-A by introducing into a reaction zone a phenolic compound reactant, a carbonyl compound reactant, and a catalyst promoter comprising bismethylthiopropane added to the reaction system in certain specific locations, and reacting the ingredients within the reaction zone in the presence of an acid catalyst.

Dibenzo[d,g][1,3]dioxocin-6-carboxylic acids substituted by methyl or ethyl or a moiety --CH2 CH2 -- at the 12-position and optionally substituted at other positions, such as methyl 4'-chlorospiro(cyclopropane-1,12'(12'H)-dibenzo[d,g][1,3]dioxocin)-6'-carboxylic acid, and their agriculturally acceptable esters, amides, and salts are useful for the control of undesirable vegetation. The 1,1-diarylcyclopropane intermediates required for the spirocyclopropane compounds can be prepared from appropriately substituted 1,1-diarylethene procursors by reaction with phenylthiomethyl lithium reagent.
