The CAS Registry Mumber 131423-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,2 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131423-35:
(8*1)+(7*3)+(6*1)+(5*4)+(4*2)+(3*3)+(2*3)+(1*5)=83
83 % 10 = 3
So 131423-35-3 is a valid CAS Registry Number.

DABCO-Catalysed Dimerisation of Some α,β-Unsaturated Esters

Drewes, Siegfried E.,Emslie, Neville D.,Karodia, Nazira

, p. 1915 - 1921 (2007/10/02)

Acrylate esters readily undergo the Baylis-Hillman reaction with aldehydes in the presence of DABCO.In the absence of aldehydes it has now been established that esters with good leaving groups undergo self condensation (Michalel addition) to afford dimers in almost quantitative yield.
