Check Digit Verification of cas no

The CAS Registry Mumber 81747-26-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,4 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81747-26:
(7*8)+(6*1)+(5*7)+(4*4)+(3*7)+(2*2)+(1*6)=144
144 % 10 = 4
So 81747-26-4 is a valid CAS Registry Number.

A brand-new Pd-mediated generation of benzyne and its [2+2+2] cycloaddition: δ-carbon elimination and concomitant decarboxylation

scheme or table, p. 6569 - 6572 (2009/04/05)

We found a brand-new method for the generation of aryne from methyl 2-bromobenzoates via the Pd-mediated concomitant δ-carbon elimination and decarboxylation. The generated arynes underwent Pd-mediated [2+2+2] cycloaddition to give triphenylenes.
