Check Digit Verification of cas no
The CAS Registry Mumber 19072-92-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,7 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19072-92:
(7*1)+(6*9)+(5*0)+(4*7)+(3*2)+(2*9)+(1*2)=115
115 % 10 = 5
So 19072-92-5 is a valid CAS Registry Number.

Facile preparation and reactivity of polystyrene-supported (dichloroiodo)benzene: A convenient recyclable reagent for chlorination and oxidation
Chen, Jiang-Min,Zeng, Xiao-Mei,Middleton, Kyle,Zhdankin, Viktor V.
supporting information; experimental part, p. 1952 - 1955 (2011/04/25)
A facile one-pot preparation of polystyrene-supported (dichloroiodo)benzene (loading of -ICl2 up to 1.35 mmol/g) from polystyrene, iodine, and bleach has been developed. This recyclable reagent is useful for efficient chlorination of organic substrates and selective oxidation of various alcohols to the corresponding carbonyl compounds in high yields under mild conditions. The final products are conveniently separated from the polymeric byproduct by simple filtration and isolated in good purity after evaporation of solvent.

, p. 2231 - 2236 (2007/10/03)
Dowex (strongly acidic cationic exchange resin) polymer is employed as solid acid catalyst for the clean and less hazardous protection of carbonyl compounds as phenylhydrazones and 2,4-dintrophenylhydrazones in ethanol under reflux conditions. The reactions proceed very smoothly and the yields of the derivatives are excellent. Copyright Taylor & Francis, Inc.
