Check Digit Verification of cas no
The CAS Registry Mumber 813-31-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 813-31:
(5*8)+(4*1)+(3*3)+(2*3)+(1*1)=60
60 % 10 = 0
So 813-31-0 is a valid CAS Registry Number.

Various synthetic approaches to fluoroalkyl p-nitrophenyl ethers
Preschera, Dietrich,Thiele, Thomas,Ruhmann, Ralf
, p. 145 - 148 (2007/10/03)
Homologous 1H,1H-perfluoroalkyl p-nitrophenyl ethers (alkyl = C2-C8) were synthesized using different methods. The results are discussed in context with contradictory comments of the literature. The fluoroalkoxylation of p-chloronitrobenzene occurs in only one step, but it is limited to small fluoroalkyl groups. The fluoroalkylation of p-nitrophenol via sulphonic acid esters is a better synthetic route. Differences in reactivity and yield between tosylates, mesylates and inflates are found and discussed. The preferred synthesis includes the use of trifluoromethane sulphonic acid esters.
