Check Digit Verification of cas no

The CAS Registry Mumber 1228231-49-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,2,3 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1228231-49:
(9*1)+(8*2)+(7*2)+(6*8)+(5*2)+(4*3)+(3*1)+(2*4)+(1*9)=129
129 % 10 = 9
So 1228231-49-9 is a valid CAS Registry Number.

Zwitterionic ladder bis(arylethenyl)benzenes with large two-photon absorption cross sections

Fukazawa, Aiko,Yamada, Hiroshi,Sasaki, Yutaka,Akiyama, Seiji,Yamaguchi, Shigehiro

supporting information; experimental part, p. 466 - 469 (2010/08/22)

Various phosphonium- and borate-bridged bis(arylethenyl)benzenes were synthesized. The large two-photon absorption (TPA) cross sections in these zwitterionic ladder π-electron systems revealed that the introduction of zwitterionic bridges in the coplanar π-conjugated framework is a powerful strategy for designing excellent TPA materials. 2010 Wiley-VCH Verlag GmbH&Co.
