18108-16-2 Usage
General Description
Phosphinic acid, phenylmethyl ester, also known as PMIDA, is an organophosphorus compound used as a pesticide and herbicide. Its chemical formula is C8H11O2P and it is a colorless liquid with a slightly fruity odor. PMIDA is used in a variety of agricultural settings to control weeds and pests, and is often formulated as a water-soluble concentrate. However, it is considered to be toxic to aquatic life and can have negative effects on non-target organisms. PMIDA is typically handled with protective equipment and its use is regulated in many countries due to its potential environmental and human health impacts.
Check Digit Verification of cas no
The CAS Registry Mumber 18108-16-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,0 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18108-16:
(7*1)+(6*8)+(5*1)+(4*0)+(3*8)+(2*1)+(1*6)=92
92 % 10 = 2
So 18108-16-2 is a valid CAS Registry Number.

Synthesis of H-Phosphonate Intermediates and Their Use in Preparing the Herbicide Glyphosate
-
Paragraph 0044; 0036, (2014/10/16)
The esterfication of hypophosphorous acid is followed by reaction with another molecule of alcohol under the action of a nickel catalyst to provide a green method for the preparation of H-phosphonate diesters. This method avoids the need for any stoichiometric chlorine unlike those based on phosphorous trichloride.
