16655-63-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16655-63-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,6,5 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 16655-63:
(7*1)+(6*6)+(5*6)+(4*5)+(3*5)+(2*6)+(1*3)=123
123 % 10 = 3
So 16655-63-3 is a valid CAS Registry Number.

Kinetic and equilibrium studies of σ-adduct formation and substitution in the reactions of sulphite ions with some alkyl and aryl ethers and thioethers

Crampton, Michael R.,Holmes, Anthony J.

, p. 787 - 792 (1998)

Kinetic and equilibrium results are reported for the reactions of sulphite with the ethyl and phenyl ethers of 2,4,6-trinitrophenol and 2,4,6-trinitrothiophenol in 80/20 (v/v) water/DMSO. In each case 1:1 and 1:2 adducts are observed by reaction of sulphite at one or two unsubstituted ring positions respectively. In the case of the ethyl derivatives these adducts are long-lived; however, the phenyl derivatives rapidly yield 2,4,6-trinitrobenzene-sulphonate, the substitution product. This difference is attributed to a change in the nature of the rate-determining step, from nucleophilic attack with the phenyl derivatives to leaving group departure with the alkyl derivatives.
