Urea, N-butyl-N-(3-chlorophenyl)-N'-cyclopropyl-, also known as Chloropropham, is a chemical compound with the molecular formula C11H14ClNO. It is a derivative of urea, featuring a cyclopropyl group, a 3-chlorophenyl group, and a butyl group attached to the nitrogen atoms. Chloropropham is primarily used as a plant growth regulator, specifically as a pre-emergence herbicide to control the growth of certain weeds in agricultural settings. It works by inhibiting the synthesis of proteins in the plant cells, thereby preventing their growth. Due to its effectiveness and relatively low toxicity to mammals, Chloropropham has been widely used in the agricultural industry to protect crops and improve yield.
The CAS Registry Mumber 64393-38-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,3,9 and 3 respectively; the second part has 2 digits, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 64393-38: (7*6)+(6*4)+(5*3)+(4*9)+(3*3)+(2*3)+(1*8)=140 140 % 10 = 0 So 64393-38-0 is a valid CAS Registry Number.
