Check Digit Verification of cas no

The CAS Registry Mumber 217652-51-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,6,5 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 217652-51:
(8*2)+(7*1)+(6*7)+(5*6)+(4*5)+(3*2)+(2*5)+(1*1)=132
132 % 10 = 2
So 217652-51-2 is a valid CAS Registry Number.

Synthesis of dibenzodiynes: Exceptionally easy formation of a chrysene biradical

Rodríguez,Rodríguez,López,Castedo,Domínguez,Saá

, p. 1282 - 1284 (2007/10/03)

The new dibenzodiynes 1 and 2 have been synthesized using a Nozaki-Hiyama-Kishi reaction as the key step. Treatment of dibenzodiynone 2 with base at -50°C afforded an enyne-cumulene intermediate that underwent a regioselective cycloaromatization via a chrysene biradical.
