Check Digit Verification of cas no

The CAS Registry Mumber 1187887-43-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,8,8 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1187887-43:
(9*1)+(8*1)+(7*8)+(6*7)+(5*8)+(4*8)+(3*7)+(2*4)+(1*3)=219
219 % 10 = 9
So 1187887-43-9 is a valid CAS Registry Number.

Synthesis and insecticidal activity of heptafluoroisopropylcontaining benzoylphenylurea structures

Zhang, Jian,Tang, Xiuhong,Ishaaya, Isaac,Song, Cao,Wu, Jingjing,Yu, Jinlong,Li, Hui,Qian, Xuhong

, p. 2736 - 2740 (2010)

Fourteen novel heptafluoroisopropyl-containing benzoylphenylureas were designed and synthesized. Their insecticidal activities against armyworm (Pseudaletia separata Walker) were examined and compared with the commercial product diflubenzuron. Three compounds (III, IIJ, and IIk) showed excellent insecticidal effect, and their activity resembled that of diflubenzuron. Compound III also showed nearly the same insecticidal activity as novaluron on African cotton leafworm (Spodoptera littoralis). Furthermore, results from a field trial indicated that 5% EC III exhibited similar efficacy in comparison with chlorfluazuron and hexaflumuron against imported cabbage worm (Pieris rapae L.) and diamondback moth (Plutella xylostella), respectively.
