Calculate Digit Verification of CAS Registry Number 28609-29:
(7*2)+(6*8)+(5*6)+(4*0)+(3*9)+(2*2)+(1*9)=132
132 % 10 = 2

Regioselective Diboron-Mediated Semireduction of Terminal Allenes

Gates, Ashley M.,Santos, Webster L.

supporting information, p. 4619 - 4624 (2019/12/11)

A method for the regioselective reduction of the terminal double bond of 1,1-disubstituted allenes has been developed. In the presence of a palladium catalyst, tetrahydroxydiboron and stoichiometric water, allene semireduction proceeds in high yield to afford Z-alkenes selectively.
