Check Digit Verification of cas no

The CAS Registry Mumber 1254942-05-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,9,4 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1254942-05:
(9*1)+(8*2)+(7*5)+(6*4)+(5*9)+(4*4)+(3*2)+(2*0)+(1*5)=156
156 % 10 = 6
So 1254942-05-6 is a valid CAS Registry Number.

Design, synthesis, and bioactivity of cyanonitrovinyl neonicotinoids as potential insecticides

Wang, Kewei,Qian, Xuhong,Cui, Jingnan

experimental part, p. 1117 - 1122 (2012/06/18)

A series of cyanonitrovinyl neonicotinoids were designed and synthesized via five steps in about 35% overall yields. All compounds were structurally characterized by 1H nuclear magnetic resonance (NMR), 13C NMR, infrared (IR), and high-resolution mass spectrometry (HRMS), and single-crystal X-ray diffraction analysis of 2-[1-[(6-chloropyridin-3-yl)methyl] -2-imidazolidinylidene]-2-nitroacetonitrile revealed that the double bond is (E)-configured. The preliminary agriculture bioassay indicated that one compound exhibited moderate insecticidal activity against pea aphid. Springer-Verlag 2010.
