N-Pentyl-N'-diphenylphosphinyl-harnstoff, also known as N-pentyl-N'-diphenylphosphinoylurea, is an organophosphorus compound with the chemical formula C17H22N2OP. It is a white crystalline solid that is soluble in organic solvents. N-Pentyl-N'-diphenylphosphinyl-harnstoff is characterized by a urea backbone, with a pentyl group attached to the nitrogen atom and a diphenylphosphinyl group attached to the other nitrogen atom. It is used as a ligand in coordination chemistry, particularly in the formation of transition metal complexes, due to its ability to chelate metals through both the nitrogen and phosphorus atoms. The compound is also of interest in the field of homogeneous catalysis, where it can be used to modify the properties of catalysts.

Check Digit Verification of cas no

The CAS Registry Mumber 6778-77-4 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 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6778-77:
(6*6)+(5*7)+(4*7)+(3*8)+(2*7)+(1*7)=144
144 % 10 = 4
So 6778-77-4 is a valid CAS Registry Number.
