The chemical compound "2-(2,4-dimethyl-phenyl)-5'-methyl-2',3'-dihydro-2λ5-spiro[benzo[1,3,2]dioxaphosphole-2,2'-[1,2]oxaphosphole]" is a complex organic molecule with a unique structure. It features a spiro ring system, which consists of two fused heterocyclic rings: a benzo[1,3,2]dioxaphosphole and a [1,2]oxaphosphole. The benzo[1,3,2]dioxaphosphole ring is characterized by a benzene ring fused with a dioxaphosphole, which contains oxygen and phosphorus atoms. The [1,2]oxaphosphole ring is a six-membered ring with one oxygen and one phosphorus atom. The molecule also has a 2,4-dimethyl-phenyl group attached to the spiro center, as well as a 5'-methyl group on the [1,2]oxaphosphole ring. 2-(2,4-dimethyl-phenyl)-5'-methyl-2',3'-dihydro-2λ5-spiro[benzo[1,3,2]dioxaphosphole-2,2'-[1,2]oxaphosphole] is an example of a phosphorus-containing heterocycle, which can have various applications in materials science and pharmaceuticals due to its electronic and steric properties.
The CAS Registry Mumber 61441-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,4,4 and 1 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 61441-54: (7*6)+(6*1)+(5*4)+(4*4)+(3*1)+(2*5)+(1*4)=101 101 % 10 = 1 So 61441-54-1 is a valid CAS Registry Number.
