Check Digit Verification of cas no

The CAS Registry Mumber 1257598-65-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,5,9 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1257598-65:
(9*1)+(8*2)+(7*5)+(6*7)+(5*5)+(4*9)+(3*8)+(2*6)+(1*5)=204
204 % 10 = 4
So 1257598-65-4 is a valid CAS Registry Number.

Synthesis and acaricidal activity of strobilurin-pyrimidine derivatives

, p. 137 - 140 (2014/02/14)

Pyriminostrobin, a new acaricide, was discovered in our previous studies. Because introducing fluorine into organic compounds can increase bioactivity, pyriminostrobin was modified as a series of strobilurin-pyrimidine derivatives for biological screening. The compounds were characterized by 1H NMR, MS and elemental analysis. Preliminary bioassays demonstrated that compounds 7e and 7i exhibited significant control against Tetranychus cinnabarinus (Boisd.) at 0.625 mg L-1, and their acaricidal potencies were higher than pyriminostrobin in a greenhouse. The relationship between structure and acaricidal activity was also studied.
