Check Digit Verification of cas no

The CAS Registry Mumber 21690-87-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,9 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21690-87:
(7*2)+(6*1)+(5*6)+(4*9)+(3*0)+(2*8)+(1*7)=109
109 % 10 = 9
So 21690-87-9 is a valid CAS Registry Number.

Hydrogen abstraction reactions of peroxydisulfuryl difluoride

Kirchmeier, Robert L.,Shreeve, Jean'ne M.

, p. 2886 - 2890 (1973)

Several new as well as a large number of known fluorosulfate-containing molecules have been synthesized via hydrogen radical abstraction with S2O6F2. In general, the reactions were moderated sufficiently to permit wide applicability of this synthetic approach by dilution of the reactants and by lowering of the temperature. Amine, alcohol, aromatic, aliphatic, perfluoroalkyl, hydrogen halide, and thiol hydrogens were easily abstracted and in most cases converted to stable fluorosulfate products.
