Check Digit Verification of cas no

The CAS Registry Mumber 26143-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,1,4 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 26143-03:
(7*2)+(6*6)+(5*1)+(4*4)+(3*3)+(2*0)+(1*3)=83
83 % 10 = 3
So 26143-03-3 is a valid CAS Registry Number.

Electroreductive coupling of aromatic acyl bromides to 1,2-diketones

Kise,Ueda

, p. 755 - 756 (2007/10/03)

The direct electroreduction of aromatic acyl bromides gave aromatic 1,2-diketones. The best result was obtained using a Pb cathode in acetonitrile containing Bu4NClO4 as a supporting electrolyte. Aromatic acyl bromides substituted by an electron-donating group afforded 1,2-diketones in moderate-to-good yields, whereas acylated endiols were formed exclusively from aromatic acyl bromides substituted by an electron-withdrawing group.
