Check Digit Verification of cas no

The CAS Registry Mumber 1000391-88-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,0,3,9 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1000391-88:
(9*1)+(8*0)+(7*0)+(6*0)+(5*3)+(4*9)+(3*1)+(2*8)+(1*8)=87
87 % 10 = 7
So 1000391-88-7 is a valid CAS Registry Number.

Two-photon absorption of a series of V-shape molecules: The influence of acceptor's strength on two-photon absorption in a noncentrosymmetric D-π-A-π-D system

experimental part, p. 4685 - 4689 (2009/09/25)

A series of V-shape D-π-A-π-D molecules were synthesized based on pyrimidine as the acceptor. The strength of the acceptor (A) in these molecules was systematically adjusted through changing the substituent group in pyrimidine. Their two-photon absorption properties were measured by two-photon induced fluorescence techniques with a mode-locked Ti:sapphire laser (100 fs, 80 MHz) in the range of 720 to 880 nm. The results indicate that the strength of the acceptor has an important influence on the two-photon absorption properties of this noncentrosymmetric D-π-A-π-D system, and a molecule with a strong acceptor is liable to display a large two-photon absorption cross-section.
