Check Digit Verification of cas no
The CAS Registry Mumber 5043-54-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,4 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5043-54:
(6*5)+(5*0)+(4*4)+(3*3)+(2*5)+(1*4)=69
69 % 10 = 9
So 5043-54-9 is a valid CAS Registry Number.

Photodecaging from 9-substituted 2,7-dihydroxy and dimethoxyfluorenes: Competition between heterolytic and homolytic pathways
Roxin, Aron,Chase, Alex,Jeffers, Elizabeth,Lukeman, Matthew
, p. 920 - 930 (2012/03/08)
2,7-Dihydroxy-9-fluorenol (9), 2,7-dimethoxy-9-fluorenol (10), and 2,7-dimethoxy-9-acetoxyfluorene (11) were prepared and their photochemistry was studied in methanol and aqueous methanol solution in the hopes of observing efficient expulsion of the substituents positioned at the 9-position. For all three compounds, the primary photoproducts were 2,7-disubstituted-9-fluorenes and 2,7-disubstituted-9-methoxyfluorenes. A mechanism of reaction is proposed for production of these products, and involves competing homolytic and heterolytic pathways that produce radical and carbocation intermediates. Reaction quantum yields (for substrate disappearance) ranged between 0.21 and 0.31.
