Check Digit Verification of cas no
The CAS Registry Mumber 49781-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,8 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 49781-49:
(7*4)+(6*9)+(5*7)+(4*8)+(3*1)+(2*4)+(1*9)=169
169 % 10 = 9
So 49781-49-9 is a valid CAS Registry Number.

Synthesis method and application of 4-oxo-trans-2-hexenal analogue
-
Paragraph 0028-0030, (2020/12/30)
The invention discloses a synthesis method and application of a 4-oxo-trans-2-hexenal analogue, and belongs to the technical field of biological prevention and control. The analogues comprise 5-methyl-4-oxo-trans-2-hexenal, 5, 5-difluoro-4-oxo-trans-2-hexenal, 4-oxo-trans-2-hexenoic acid, 4-oxo-trans-2-hexenol and 4-hydroxy-trans-2-hexenal. One or more of the five compounds completely replace 4-oxo-trans-2-hexenal in sex pheromone components of apolygus lucorum, lygus pratensis and apolygus lucorum. The synthesis methods of the 5-methyl-4-oxo-trans-2-hexenal and the 5, 5-difluoro-4-oxo-trans-2-hexenal are found for the first time, the application composition can significantly reduce the release rate of the lure, prolong the trapping time and save the cost, the problem that the 4-oxo-trans-2-hexenal is unstable in the field can be avoided, and the application range of the 5-methyl-4-oxo-trans-2-hexenal is widened. Male insects such as apolygus lucorum, herbage miridae and apolygus lucorum can be trapped and killed more effectively.
