N-cyanocarbamimidoyl-glycine, also known as dicyandiamide (DCD), is a chemical compound with the formula NH2-CO-NH-CN. It is a white crystalline solid that is widely used as a soil amendment to inhibit the conversion of urea into ammonia, thereby reducing nitrogen loss and improving the efficiency of nitrogen fertilizers. DCD is also employed in the production of melamine, a polymer used in various applications such as plastics, laminates, and adhesives. It is important to note that while DCD has agricultural and industrial applications, it is also considered a hazardous substance and requires proper handling and disposal to minimize environmental and health risks.
The CAS Registry Mumber 6779-78-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,7 and 9 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 6779-78: (6*6)+(5*7)+(4*7)+(3*9)+(2*7)+(1*8)=148 148 % 10 = 8 So 6779-78-8 is a valid CAS Registry Number.
