Urea, N,N-bis(1-methylpropyl)-N'-phenyl-, also known as diphenamid, is a chemical compound with the formula C17H24N2O. It is a white crystalline solid that is widely used as a selective pre-emergence herbicide in agriculture, particularly for controlling annual grasses and broadleaf weeds in crops such as cotton, soybeans, and potatoes. Diphenamid works by inhibiting cell division in the meristematic tissues of plants, leading to their death. It is known for its low toxicity to mammals and is considered relatively safe for use in the environment. The chemical is also characterized by its high solubility in water and its ability to bind to soil particles, which helps in its targeted application and reduces the risk of runoff.

Check Digit Verification of cas no

The CAS Registry Mumber 53463-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,4,6 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 53463-31:
(7*5)+(6*3)+(5*4)+(4*6)+(3*3)+(2*3)+(1*1)=113
113 % 10 = 3
So 53463-31-3 is a valid CAS Registry Number.

Phenylureas. Part 1. Mechanism of the basic hydrolysis of phenylureas

Laudien,Mitzner

, p. 2226 - 2229 (2007/10/03)

The mechanism of the hydrolytic decomposition of phenylureas in basic media in the pH range 12 to 14 is investigated. In this pH range a levelling of the rate-pH curve is observed as well as a change of the substituent influence on the hydrolysis rate. These experimental findings suggest the formation of an unreactive side product of the phenylurea in a parasitic side equilibrium at sufficiently high pH. The urea dissociates at the aryl-NH group to give its conjugate base. For the hydrolytic decomposition of phenylureas an addition-elimination mechanism is proposed as has been established for the alkaline hydrolysis of carboxylic acid esters and amides.
