Check Digit Verification of cas no
The CAS Registry Mumber 83192-87-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,9 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 83192-87:
(7*8)+(6*3)+(5*1)+(4*9)+(3*2)+(2*8)+(1*7)=144
144 % 10 = 4
So 83192-87-4 is a valid CAS Registry Number.

In order to obtain fluorinated difunctional monomers for fluoropolyurethanes, we synthesized novel fluorinated aliphatic diisocyanates (OCNCH2(CF2)nCH2NCO) from corresponding diols (HOCH2CH2(CF2)nCH2CH2OH).Oxidation of the diols with chromium trioxide-sulfuric acid gave α,α,ω,ω-tetrahydroperfluoroalkylene dicarboxylic acids in high yields.Then treating the acids with phosphorus pentachloride afforded corresponding dicarboxyl chlorides, which are easily converted to dicarboxyl azides with hydrazoic acid-pyridine complex.Finally, on Curtius rearrangement of the azides, the end products, α,α,ω,ω-tetrahydroperfluoroalkylene diisocyanates were obtained in 53percent (n=4) and 19percent (n=6) yields from the starting diols.
