Check Digit Verification of cas no
The CAS Registry Mumber 143287-95-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,8 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 143287-95:
(8*1)+(7*4)+(6*3)+(5*2)+(4*8)+(3*7)+(2*9)+(1*5)=140
140 % 10 = 0
So 143287-95-0 is a valid CAS Registry Number.

Palladium-Catalysed Hydroxycarbonylation of Vinyl and Aryl Triflates: Synthesis of α,β-Unsaturated and Aromatic Carboxylic Acids
Cacchi, Sandro,Lupi, Alessandro
, p. 3939 - 3942 (1992)
The palladium-catalysed hydroxycarbonylation of vinyl and aryl triflates, under a CO balloon, in the presence of potassium acetate affords α,β-unsaturated and aromatic carboxylic acids with one more carbon in good to high yield.The nature of the solvent and of the ligand have been proved to be crucial for the success of the reaction.Vinyl triflates undergo the hydroxycarbonylation at room temperature in DMF in the presence of Pd(OAc)2(PPh3)2.Aryl triflates produce best results at 60 deg C in DMSO in the presence of Pd(OAc)2 and 1,1-bis(diphenylphosphino)ferrocene (dppf).
