Check Digit Verification of cas no

The CAS Registry Mumber 1089700-47-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,9,7,0 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1089700-47:
(9*1)+(8*0)+(7*8)+(6*9)+(5*7)+(4*0)+(3*0)+(2*4)+(1*7)=169
169 % 10 = 9
So 1089700-47-9 is a valid CAS Registry Number.

Synthesis and critical micelle concentration of a series of gemini alkylphenol polyoxyethylene nonionic surfactants

Yang, Fang,Li, Gang,Xu, Nian,Liu, Rong,Zhang, Song-Mei,Wu, Zeng-Jiang

, p. 339 - 345 (2011)

A series of gemini n-alkylphenol polyoxyethylene surfactants (GAP) were successfully synthesized and their molecular structure were confirmed by NMR and FTIR spectrum. Using the same synthesis route, a Gemini nonylphenol polyoxyethylene surfactant (GNP) was synthesized using an industrial nonylphenol product and paraformaldehyde, and its molecular structure was also characterized by 1H-NMR and FTIR spectra. The optimal reaction conditions were established. The critical micelle concentration (CMC) values of GAP were determined by means of Wilhelmy plate method and steady-state fluorescence probe method. The experimental results show how the lengths of the hydrophilic polyoxyethylene chain and the hydrophobic tail alter the CMC values. The CMC values of the GAP are found to be much lower than those of corresponding conventional single tail nonionic surfactants of the polyethoxylated alkylphenol type, which indicates that the gemini species exhibit a better surface activity.
