Check Digit Verification of cas no

The CAS Registry Mumber 59209-71-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,2,0 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 59209-71:
(7*5)+(6*9)+(5*2)+(4*0)+(3*9)+(2*7)+(1*1)=141
141 % 10 = 1
So 59209-71-1 is a valid CAS Registry Number.

Regioselective semihydrogenation of dienes

Graham, Thomas J. A.,Poole, Thomas H.,Reese, Charles N.,Goess, Brian C.

, p. 4132 - 4138 (2011/07/07)

A one-pot, three-step strategy for the regioselective semihydrogenation of dienes is described. This procedure uses 9-BBN-H as a temporary protective group for alkenes. Yields range from 55% to 95%, and the reaction is tolerant of a variety of common functional groups. Additionally, the final elimination step of the sequence can be replaced with a peroxide-mediated alkylborane oxidation, generating regioselectively semihydrogenated product alcohols.
