Calculate Digit Verification of CAS Registry Number 117754-20:
(8*1)+(7*1)+(6*7)+(5*7)+(4*5)+(3*4)+(2*2)+(1*0)=128
128 % 10 = 8
So 117754-20-8 is a valid CAS Registry Number.

Free-Radical Selenosulfonation of Vinylcyclopropanes, a Cyclopropylidene, and Cyclopropylacetylene. Relative Rates of Chain-Transfer, Ring-Opening, and Inversion in Radical Intermediates

Back, Thomas G.,Muralidharan, K. Raman

, p. 121 - 125 (2007/10/02)

The free-radical selenosulfonation of vinylcyclopropanes 4a-e and cyclopropylidene 9 was accompanied by ring-opening to afford 1,5- and 1,3-adducts 7a-e and 11, respectively, whereas cyclopropylacetylene (13) gave predominantly 1,2-addition to afford 15.T
