Check Digit Verification of cas no

The CAS Registry Mumber 1234618-74-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,6,1 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1234618-74:
(9*1)+(8*2)+(7*3)+(6*4)+(5*6)+(4*1)+(3*8)+(2*7)+(1*4)=146
146 % 10 = 6
So 1234618-74-6 is a valid CAS Registry Number.

Cis-nitenpyram analogues containing 1,4-dihydropyridine: Synthesis, insecticidal activities, and molecular docking studies

Sun, Chuanwen,Chen, Yanxia,Liu, Tianyan,Wu, Ying,Fang, Ting,Wang, Jing,Xing, Jiahua

, p. 1415 - 1422 (2012)

A novel series of cis-nitenpyram analogues (2a-2p) were designed and prepared by introducing the 1,4-dihydropyridine, with their cis-configuration confirmed by X-ray diffraction. Preliminary bioassays showed that most compounds exhibited good insecticidal activities at 20 mg/L against Aphis medicagini, and analogues 2a and 2d afforded the best activity, and both of them had 100% mortality at 4 mg/L. In addition, molecular docking studies were also performed to model the ligand-receptor complexes, and the results explained the structure-activity relationships observed in vitro, which may provide some useful information for future design of new insecticides.
