Pent-4-enyl-phenyl-(phenylcarbamoyl)-phosphin is a complex organic compound with the molecular formula C20H20NO2P. It is characterized by a pent-4-enyl group, which is a five-carbon chain with a double bond at the fourth position, attached to a phenyl ring. This phenyl ring is further connected to a phenylcarbamoyl group, which consists of a phenyl ring and an amide group (-CO-NH2). The entire structure is completed by a phosphorus atom bonded to the phenyl ring, forming a phosphin group. Pent-4-enyl-phenyl-(phenylcarbamoyl)-phosphin is likely to be used in the synthesis of various pharmaceuticals or as an intermediate in organic chemistry due to its unique structure and potential reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 5541-50-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,4 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5541-50:
(6*5)+(5*5)+(4*4)+(3*1)+(2*5)+(1*0)=84
84 % 10 = 4
So 5541-50-4 is a valid CAS Registry Number.
