4H-Pyrido[1,2-a]pyrimidine-3-carbonyl chloride, 6,7,8,9-tetrahydro-6-methyl-4-oxo-9-(phenylmethylene)-, (E)- is a complex organic compound with the molecular formula C16H14N4O2Cl. It is characterized by a pyrido[1,2-a]pyrimidine core, which is a fused ring system consisting of a pyridine and a pyrimidine. The compound features a carbonyl chloride group attached to the 3-position of the pyrido[1,2-a]pyrimidine ring. Additionally, it has a tetrahydro-6-methyl-4-oxo-9-(phenylmethylene) moiety, indicating a fully saturated six-membered ring with a methyl group at the 6-position, a carbonyl group at the 4-position, and a phenylmethylene group (a phenyl group double-bonded to a methylene group) at the 9-position. The (E)- configuration specifies the geometric isomerism of the phenylmethylene double bond, which is in the E configuration, meaning the highest priority substituents are on opposite sides of the double bond. 4H-Pyrido[1,2-a]pyrimidine-3-carbonyl chloride,
6,7,8,9-tetrahydro-6-methyl-4-oxo-9-(phenylmethylene)-, (E)- is likely to be used in the synthesis of various pharmaceuticals and other organic compounds due to its unique structure and reactivity.
The CAS Registry Mumber 93886-09-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,8,8 and 6 respectively; the second part has 2 digits, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 93886-09: (7*9)+(6*3)+(5*8)+(4*8)+(3*6)+(2*0)+(1*9)=180 180 % 10 = 0 So 93886-09-0 is a valid CAS Registry Number.
