16554-83-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16554-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,5,5 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 16554-83:
(7*1)+(6*6)+(5*5)+(4*5)+(3*4)+(2*8)+(1*3)=119
119 % 10 = 9
So 16554-83-9 is a valid CAS Registry Number.

Stereochemistry of the Diels-Alder Reaction of Butadiene with Cyclopropene

Baldwin, John E.,Reddy, V. Prakash

, p. 5264 - 5267 (1989)

1(E)-Deuteriobutadiene and cyclopropene react at 0 deg C to give 2-endo-deuteriobicyclohept-3-ene; 1(Z)-deuteriobutadiene leads to the 2-exo-deuterio bicyclic product.Analysis of these products through 2H NMR spectroscopy reveals complete stereospecificity, indicating that the transition structure having an endo orientation of diene and cyclopropene is strongly favored over the alternative exo geometry.

Desaturase reactions complicate the use of norcarane as a mechanistic probe. Unraveling the mixture of twenty-plus products formed in enzyme-catalyzed oxidations of norcarane

Newcomb, Martin,Chandrasena, R. Esala P.,Lansakara-P, Dharmika S. P.,Kim, Hye-Yeong,Lippard, Stephen J.,Beauvais, Laurance G.,Murray, Leslie J.,Izzo, Viviana,Hollenberg, Paul F.,Coon, Minor J.

, p. 1121 - 1127 (2007/10/03)

(Chemical Equation Presented) Norcarane, bicyclo[4.1.0]heptane, has been widely used as a mechanistic probe in studies of oxidations catalyzed by several iron-containing enzymes. We report here that, in addition to oxygenated products, norcarane is also oxidized by iron-containing enzymes in desaturase reactions that give 2-norcarene and 3-norcarene. Furthermore, secondary products from further oxidation reactions of the norcarenes are produced in yields that are comparable to those of the minor products from oxidation of the norcarane. We studied oxidations catalyzed by a representative spectrum of iron-containing enzymes including four cytochrome P450 enzymes, CYP2B1, CYPΔ2B4, CYPΔ2E1, and CYPΔ2E1 T303A, and three diiron enzymes, soluble methane monooxygenase (sMMO) from Methylococcus capsulatus (Bath), toluene monooxygenase (ToMO) from Pseudomonas stutzeri OX1, and phenol hydroxylase (PH) from Pseudomonas stutzeri OX1. 2-Norcarene and 3-norcarene and their oxidation products were found in all reaction mixtures, accounting for up to half of the oxidation products in some cases. In total, more than 20 oxidation products were identified from the enzyme-catalyzed reactions of norcarane. The putative radical-derived product from the oxidation of norcarane, 3- hydroxymethylcyclohexene (21), and the putative cation-derived product from the oxidation of norcarane, cyclohept-3-enol (22), coelute with other oxidation products on low-polarity GC columns. The yields of product 21 found in this study are smaller than those previously reported for the same or similar enzymes in studies where the products from norcarene oxidations were ignored, and therefore, the limiting values for lifetimes of radical intermediates produced in the enzyme-catalyzed oxidation reactions are shorter than those previously reported.

PHOTOLYSIS OF THE AZOALKANE 2,3-DIAZATRICYCLO4,9>NON-2-ENE: DIRECT OBSERVATION OF 4-CYCLOHEXENYLDIAZOMETHANE

Adam, Waldemar,Carballeira, Nestor,Gillaspey, William D.

, p. 5473 - 5476 (2007/10/02)

Besides denitrogenation to the tricycloalkane 8, the photolysis of azoalkane 3 affords the diazoalkane 4, which serves as precursor to the minor hydrocarbon products 9, 10 and 11; irradiation of azoalkane 3 with the 333.6 nm line of an 18-W argon ion laser was essential to obtain preparative quantities of diazoalkane 4 for its detection and identification.
