Check Digit Verification of cas no

The CAS Registry Mumber 61488-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,4,8 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 61488-89:
(7*6)+(6*1)+(5*4)+(4*8)+(3*8)+(2*8)+(1*9)=149
149 % 10 = 9
So 61488-89-9 is a valid CAS Registry Number.

Synthesis and structure-activity relationships of benzophenone hydrazone derivatives with insecticidal activity

Boeger, Manfred,Duerr, Dieter,Gsell, Laurenz,Hall, Roger G.,Karrer, Friedrich,Kristiansen, Odd,Maienfisch, Peter,Pascual, Alfons,Rindlisbacher, Alfred

, p. 191 - 202 (2007/10/03)

A broad range of benzophenone hydrazone derivatives was prepared and tested against selected chewing insect pests, allowing the analysis of structure-activity relationships. Good activity was found only when the aromatic rings were substituted at the 4-positions with an halogen atom and a triflate or perhaloalkoxy group. In contrast, a number of substituents on the hydrazone part led to active compounds, the best results being achieved with acyl-type substituents. The excellent laboratory and greenhouse activity of the best representatives was confirmed in semi-field trials against Spodoptera littoralis. ° 2001 Society of Chemical Industry.
