Check Digit Verification of cas no

The CAS Registry Mumber 1203559-22-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,3,5,5 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1203559-22:
(9*1)+(8*2)+(7*0)+(6*3)+(5*5)+(4*5)+(3*9)+(2*2)+(1*2)=121
121 % 10 = 1
So 1203559-22-1 is a valid CAS Registry Number.

Design, synthesis, and insecticidal activities of new N-benzoyl-N'-phenyl- N'-sulfenylureas

experimental part, p. 3661 - 3668 (2010/06/19)

Aseries of new N'-alkylaminothio,N'-arylaminothio (or dithio), and N',N'-thio (or dithio) derivatives ofN'-benzoyl-N'-phenylureas were designed and synthesized as insect-growth regulators with sulfur dichloride or disulfur dichloride as the original reactant. The new compounds were identified by 1H nuclear magnetic resonancee (NMR) spectroscopy, elemental analysis [or high-resolution mass spectrometry (HRMS)], and single-crystal X-ray diffraction analysis. The X-ray results demonstrated that there exist N-S-N or N-S-S-N bonds in these new compounds. In comparison to the parent N-benzoyl-N'-phenylureas, these derivatives displayed better solubility. The insecticidal activities of the target compounds were evaluated. The results of bioassays showed that compounds 1-24 retained the larvicidal activities of the corresponding benzoylphenylureas (BPUs) and some compounds exhibited better larvicidal activities against oriental armyworm and mosquitoes than the parent BPUs. The larvicidal activities of the selected target compounds 1 and 24 against diamondback moth were better than that of the corresponding parent compounds E and triflumuron.
