2,2-Dicyanocyclopropane-1-carboxylic acid, also known as DCPA, is a chemical compound with the formula C6H6N2O2. It is a white crystalline solid that is widely used as a pre-emergent herbicide to control a broad spectrum of annual grasses and certain broadleaf weeds. DCPA works by inhibiting plant cell division, preventing the growth of weeds. It is applied to the soil before planting and is absorbed by the roots of germinating weeds, leading to their death. DCPA is also known for its long-lasting residual activity, which can provide weed control for several months. It is used in various agricultural settings, including turf, ornamentals, and some food crops, and is considered a valuable tool in integrated weed management strategies.

The CAS Registry Mumber 5271-91-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,7 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.Calculate Digit Verification of CAS Registry Number 5271-91:
(6*5)+(5*2)+(4*7)+(3*1)+(2*9)+(1*1)=90
90 % 10 = 0
So 5271-91-0 is a valid CAS Registry Number.
