Check Digit Verification of cas no

The CAS Registry Mumber 1381787-98-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,1,7,8 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1381787-98:
(9*1)+(8*3)+(7*8)+(6*1)+(5*7)+(4*8)+(3*7)+(2*9)+(1*8)=209
209 % 10 = 9
So 1381787-98-9 is a valid CAS Registry Number.

Proacetylenic reactivity of a push-pull buta-1,2,3-triene: New chromophores and supramolecular systems

Wu, Yi-Lin,Tancini, Francesca,Schweizer, W. Bernd,Paunescu, Daniela,Boudon, Corinne,Gisselbrecht, Jean-Paul,Jarowski, Peter D.,Dalcanale, Enrico,Diederich, Francois

, p. 1185 - 1190 (2012)

Proacetylenic: An aniline-based donor-acceptor-substituted butatriene exhibits not only cumulene-like dimerization to give a [4]radialene (λmax=756 nm), but also acetylene-like (proacetylenic) reactivity towards tetracyanoethene, affording via [2+2] cycloaddition- cycloreversion a NIR-absorbing zwitterionic chromophore (λmax= 825 nm). The cationic charge on the imminium-type nitrogen in the zwitterion is evidenced by host-guest complexation with a tetraphosphonate cavitand. Copyright
