Check Digit Verification of cas no
The CAS Registry Mumber 51932-77-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,9,3 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51932-77:
(7*5)+(6*1)+(5*9)+(4*3)+(3*2)+(2*7)+(1*7)=125
125 % 10 = 5
So 51932-77-5 is a valid CAS Registry Number.

Pd(II)-Catalyzed Enantioselective Desymmetrization of Polycyclic Cyclohexenediones: Conjugate Addition versus Oxidative Heck
Lamb, Claire J. C.,Vilela, Filipe,Lee, Ai-Lan
, p. 8689 - 8694 (2019/11/03)
Pd(II)-catalyzed desymmetrization of polycyclic cyclohexenediones has been achieved with high enantio- and diastereoselectivities. Up to five contiguous stereocenters are desymmetrized, while simultaneously, an additional stereocenter is created by the enantioselective conjugate addition. Surprisingly, the conjugate addition products dominate even under typical oxidative Heck conditions, and these observations may provide some insight into the competition between the two related reactions.
Steric Effects in the Dimerization of 2,5-Dialkyl-3,4-Diphenylcyclopentadienones
Weiss, Hilton M.
