504-66-5 Usage
General Description
Dicyanamide, also known as dicyandiamide, is a chemical compound with the formula C2H4N4. It is a white, odorless, crystalline solid that is soluble in water and polar organic solvents. Dicyanamide is commonly used as a curing agent for epoxy resins, as a flame retardant in plastics and polymers, and as a nitrogen fertilizer. It is also used in the synthesis of pharmaceuticals and other organic compounds. Dicyanamide has low toxicity and is considered to be environmentally friendly, making it a popular choice for various industrial applications. However, prolonged exposure to dicyanamide dust or vapors should be avoided as it may cause irritation to the respiratory system and skin.
Check Digit Verification of cas no
The CAS Registry Mumber 504-66-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 504-66:
(5*5)+(4*0)+(3*4)+(2*6)+(1*6)=55
55 % 10 = 5
So 504-66-5 is a valid CAS Registry Number.

(Figure Presented) Extreme chemistry: The carbon nitride imide C 2N2(NH) is synthesized from the single-source precursor 1-cyanoguanidine under high-pressure and high-temperature conditions in a laser-heated diamond-anvil cell. Characterization of single crystals recovered at ambient conditions reveals that the new compound adopts a defect wurtzite structure (see picture).
