Check Digit Verification of cas no
The CAS Registry Mumber 16083-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,0,8 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16083-20:
(7*1)+(6*6)+(5*0)+(4*8)+(3*3)+(2*2)+(1*0)=88
88 % 10 = 8
So 16083-20-8 is a valid CAS Registry Number.

Isobutylene-rich macromonomers: Dynamics and yields of peroxide-initiated crosslinking
Dakin, Jackson M.,Shanmugam, Karthik Vikram Siva,Twigg, Christopher,Whitney, Ralph A.,Parent, J. Scott
, p. 123 - 132 (2015)
New isobutylene-rich elastomers bearing multiple pendant styrenic, acrylic, maleimidic, vinylic, and allylic functional groups have been prepared and examined in the context of peroxide-initiated crosslinking. Halide displacement from brominated poly(isobutylene-co-isoprene) (BIIR) by the requisite carboxylate nucleophiles in homogeneous toluene solutions provide the desired esters in quantitative yield without complications from dehydrohalogenation or premature crosslinking. Heating the resulting macromonomers with dicumyl peroxide to 160 °C under solvent-free conditions gives thermoset derivatives, with reaction rates and yields depending markedly on functional group structure. In general, high cure extents can only be achieved using highly reactive pendant functional groups, owing to the competitive balance between crosslinking through C=C oligomerization, and degradation through β-scission of backbone macroradical intermediates. Independent control of crosslinking rates and cure extents is gained through the use of nitroxyl radical traps bearing acrylate functionality.
