Check Digit Verification of cas no

The CAS Registry Mumber 21405-60-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,0 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21405-60:
(7*2)+(6*1)+(5*4)+(4*0)+(3*5)+(2*6)+(1*0)=67
67 % 10 = 7
So 21405-60-7 is a valid CAS Registry Number.

Synthesis and insecticidal activity of mesoionic pyrido[1,2-α]pyrimidinone derivatives containing a neonicotinoid moiety

Pan, Jianke,Yu, Lu,Liu, Dengyue,Hu, Deyu

, (2018/05/30)

Mesoionic pyrido[1,2-α]pyrimidinone derivatives containing a neonicotinoid moiety were designed, synthesized, and evaluated for their insecticidal activity. Some of the title compounds showed remarkable insecticidal properties against Aphis craccivora. Compound I13 exhibited satisfactory insecticidal activity against A. craccivora. Meanwhile, label-free proteomics analysis of compound I13 treatment identified a total of 821 proteins. Of these, 35 proteins were up-regulated, whereas 108 proteins were down-regulated. Differential expressions of these proteins reflected a change in cellular structure and metabolism.
