Check Digit Verification of cas no

The CAS Registry Mumber 1428438-43-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,4,3 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1428438-43:
(9*1)+(8*4)+(7*2)+(6*8)+(5*4)+(4*3)+(3*8)+(2*4)+(1*3)=170
170 % 10 = 0
So 1428438-43-0 is a valid CAS Registry Number.

Synthesis, crystal structure and biological activity of novel diester cyclophanes

Zhang, Pengfei,Yang, Bingqin,Fang, Xianwen,Cheng, Zhao,Yang, Meipan

, p. 1771 - 1775 (2013/03/13)

A series of novel diester cyclophanes was synthesized by esterification of 1,2-benzenedicarbonyl chloride with eight different diols under high dilution conditions. The structures of the compounds were verified by elemental analysis, 1H nuclear magnetic resonance (NMR), IR spectroscopy and high resolution mass spectrometry (HRMS). The crystal structures of two compounds were characterized by single crystal X-ray diffractometry (XRD). All the new cyclophanes were evaluated for biological activities and the results showed that some of these compounds have low antibacterial or antifungal activities.
