135186-78-6 Usage
Description
PYRIFTALID is a pyrimidinyloxybenzoic herbicide specifically designed for the control of grass weeds in rice crops. It operates by inhibiting the biosynthesis of amino acids in weeds, thereby effectively managing their growth. PYRIFTALID is characterized by its chemical properties, with a melting point of 159~160℃.
Uses
Used in Agricultural Industry:
PYRIFTALID is used as a herbicide for the control of grass weeds in rice crops. Its application reason is to inhibit the biosynthesis of amino acids in weeds, leading to more effective weed management and potentially increasing the yield and quality of rice.
Check Digit Verification of cas no
The CAS Registry Mumber 135186-78-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,1,8 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 135186-78:
(8*1)+(7*3)+(6*5)+(5*1)+(4*8)+(3*6)+(2*7)+(1*8)=136
136 % 10 = 6
So 135186-78-6 is a valid CAS Registry Number.

A series of novel types of 7-(4,6-dimethoxypyrimidin-2-yl)oxy - and -thio-3-methyl-1 (3H)-isobenzofuranones were discovered at Dr R Maag AG. From the thio-isobenzofuranyl series, CGA 279 233 - BSI-proposed common name pyriftalid - was chosen for further development as a grass herbicide for use in rice. General synthetic approaches to these new phthalic acid-derived compounds are given, with emphasis on the synthesis of pyriftalid and its physico-chemical behaviour.
