Check Digit Verification of cas no

The CAS Registry Mumber 1375478-29-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,5,4,7 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1375478-29:
(9*1)+(8*3)+(7*7)+(6*5)+(5*4)+(4*7)+(3*8)+(2*2)+(1*9)=197
197 % 10 = 7
So 1375478-29-7 is a valid CAS Registry Number.

Synthesis, spectroscopic characteristic of novel fluorescent dyes of pyrazoline compounds

Wang, Hai-Ying,Zhang, Xiao-Xiao,Shi, Jing-Jing,Chen, Gang,Xu, Xiao-Ping,Ji, Shun-Jun

, p. 343 - 347 (2012/06/04)

Four novel fluorescence dyes of the pyrazoline were synthesized and fully characterized by means of 1H, 13C NMR, and HRMS. The optical, electrochemical properties were also investigated. Solvent effect on the fluorescence characteristics of the four compounds indicates that the emission wavelength was red-shifted with the increase of solvent polarity. As we expected, the results indicated that these compounds exhibited high quantum yields. Quantum chemical calculations were used to obtain optimized ground-state geometry, spatial distributions of the HOMO, LUMO levels of the compounds.
