Check Digit Verification of cas no

The CAS Registry Mumber 1609543-06-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,5,4 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1609543-06:
(9*1)+(8*6)+(7*0)+(6*9)+(5*5)+(4*4)+(3*3)+(2*0)+(1*6)=167
167 % 10 = 7
So 1609543-06-7 is a valid CAS Registry Number.

Aza-crown ether derivatives based on stilbene: Two-photon absorption and bioimaging

Li, Wei,Yang, Mingdi,Wang, Linpan,Zhu, Weiju,Ye, Lina,Wu, Jieying,Tian, Yupeng,Zhou, Hongping

, p. 133 - 139 (2014)

Two novel aza-crown ether derivatives based on stilbene were synthesized and characterized. Their linear photophysical properties were systematically investigated in various solvents. The nonlinear photophysical properties were investigated by two-photon induced fluorescence method. The two-photon absorption cross sections values measured by two-photon excited fluorescence were determined to be 328.2 GM and 246.55 GM for the dyes derived from monoaza 15-crown-5 and 18-crown-6, respectively, which accorded with dipole moment changes under photoexcitation. In addition, a single-photon fluorescence cell imaging experiment proved that dye derived from monoaza 15-crown-5 was suitable for biomedical imaging.
