Check Digit Verification of cas no
The CAS Registry Mumber 2390-54-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,9 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2390-54:
(6*2)+(5*3)+(4*9)+(3*0)+(2*5)+(1*4)=77
77 % 10 = 7
So 2390-54-7 is a valid CAS Registry Number.

Phototoxic insecticidal composition and method for controlling insect populations
-
, (2008/06/13)
A phototoxic insecticidal composition includes at least one photoactive dye present in the amount of between 0.025%-4.0% of the composition, an attractant compound and/or feeding stimulant and at least one adjuvant, whereby the adjuvant interacts with the photoactive dye and insect membranes to alter the toxicity of the composition once ingested by the insect.
