Check Digit Verification of cas no

The CAS Registry Mumber 20842-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,4 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20842-80:
(7*2)+(6*0)+(5*8)+(4*4)+(3*2)+(2*8)+(1*0)=92
92 % 10 = 2
So 20842-80-2 is a valid CAS Registry Number.

Unexpected dimerization during hydrogenation of 2-(2-pyridylmethylene)-3(2H)-benzofuran-3-ones

Mák, Marianna,Nógrádi, Mihály,Sz?llosy, áron

, p. 8425 - 8429 (2006)

Palladium catalyzed hydrogenation of 2-(2-pyridylmethylene)-3(2H)-benzofuran-3-ones (1-3) gave besides the expected 2,α-dihydro products 8-10 pentacyclic dimers formed by an attack of a semihydrogenated species on the substrate.
