408359-97-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 408359-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,8,3,5 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 408359-97:
(8*4)+(7*0)+(6*8)+(5*3)+(4*5)+(3*9)+(2*9)+(1*7)=167
167 % 10 = 7
So 408359-97-7 is a valid CAS Registry Number.

supporting information; experimental part, p. 5859 - 5861 (2010/01/31)

Novel donor-π-bridge-acceptor-π-bridge-donor (D-π-A-π-D)-type 1,4-diketo-3,6-diphenylpyrrolo[3,4-c]pyrrole (DPP) derivatives with end-capping diphenylamine groups have been synthesized and shown to exhibit large two-photon absorption cross-sections over a wide range of wavelengths with strong two-photon excitation red fluorescence.
