Check Digit Verification of cas no

The CAS Registry Mumber 882507-66-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,2,5,0 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 882507-66:
(8*8)+(7*8)+(6*2)+(5*5)+(4*0)+(3*7)+(2*6)+(1*6)=196
196 % 10 = 6
So 882507-66-6 is a valid CAS Registry Number.

3-Zinciobenzofuran and 3-zincioindole: Versatile tools for the construction of conjugated structures containing multiple benzoheterole units

Nakamura, Masaharu,Ilies, Laurean,Otsubo, Saika,Nakamura, Eiichi

, p. 944 - 947 (2006)

(Chemical Equation Presented) Closing the ring: Thermally stable but reactive 3-zinciobenzofurans and indoles were synthesized by metalative cyclization of 2-ynyl phenols or anilines. Furthermore, a variety of extended π-conjugated molecules were obtained by Pd-catalyzed cross-coupling reactions of these heterocycles with mono- or polyhalo-substituted arenes and alkenes (R2Haln; see scheme; Bn = benzyl).
