Check Digit Verification of cas no

The CAS Registry Mumber 115097-75-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,0,9 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 115097-75:
(8*1)+(7*1)+(6*5)+(5*0)+(4*9)+(3*7)+(2*7)+(1*5)=121
121 % 10 = 1
So 115097-75-1 is a valid CAS Registry Number.

Synthesis and Evaluation of Fluorescent Materials for Colour Control of Peroxyoxalate Chemiluminescence. I. The Phenylethynylation of Anthraquinone

Hanhela, Peter J.,Paul, D. Brenton

, p. 1669 - 1686 (2007/10/02)

The synthesis of 9,10-bis(phenylethynyl)anthracene has been examined in detail prior to the synthesis of a series of phenylethynyl substituted aromatic compounds which are of interest as fluorescent materials for peroxyoxalate chemiluminescence.Reductions of the 9,10-bis(phenylethynyl)-9,10-dihydroanthracene-9,10-diol precursor by stannous chloride and by sodium hypophosphite-potassium iodide both gave a series of byproducts, in addition to 9,10-bis(phenylethynyl)anthracene.The formation of these compounds is interpreted in terms of a free-radical process.The interaction of 10-hydroxy-10-(phenylethynyl)anthrone with both the reducing systems has been rationalized and the reaction with concentrated sulfuric acid reinterpreted.
