118787-19-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118787-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,7,8 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118787-19:
(8*1)+(7*1)+(6*8)+(5*7)+(4*8)+(3*7)+(2*1)+(1*9)=162
162 % 10 = 2
So 118787-19-2 is a valid CAS Registry Number.

Radiochemical stability of the dicyclohexano-18-crown-6 ether (DCH18C6): Synthesis and tests in radioactive medium of the DCH18C6 radiolytic products

Draye, Micheline,Favre-Reguillon, Alain,Chomel, Rodolph,Faure, Rene,Guy, Alain,Foos, Jacques,Lemaire, Marc

, p. 183 - 197 (2007/10/03)

The cis-syn-cis isomer of the dicyclohexano-18-crown-6 ether (DCH18C6) was subjected to hydrolysis and radiolysis with a 137Cs gamma source, at different doses of irradiation. The cis-syn-cis DCH18C6 radiolytic products previously identified [1], were synthesized in their different configurations. These radiolytic products, all of cis configuration, were tested on aqueous synthetic solutions of spent nuclear fuels. Experiments in radioactive medium showed that, under continuous extraction conditions, the cis-syn-cis DCH18C6 radiolytic products cannot perturb a reprocessing process using the DCH18C6 as selective extractant. Good prospects for the application of DCH18C6 to spent nuclear fuel reprocessing were therefore demonstrated. An X-ray crystallographic study of the DCH18C6 cis-syn-cis-isomer with uranyl nitrate was investigated. Elsevier,.
