83357-58-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83357-58-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,5 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83357-58:
(7*8)+(6*3)+(5*3)+(4*5)+(3*7)+(2*5)+(1*8)=148
148 % 10 = 8
So 83357-58-8 is a valid CAS Registry Number.

Deamination Reactions, 37. Decomposition of Bicyclononane- and Bicyclonon-2-ene-9-diazonium Ions

Kirmse, Wolfgang,Hellwig, Georg

, p. 2744 - 2754 (2007/10/02)

Bicyclononane-exo-9-diazonium ions (9) have been generated from the corresponding nitrosourea (8) and base.In weakly alkaline solution (E)-3-methoxycyclononene (11) was formed by disrotatory ring opening of (9).In the presence of sodium methoxide 1,2-cyclononadiene (13) and exo-9-methoxybicyclononane (15) were additional products, presumably arising via carbene 12.Bicyclonon-2-ene-exo-9-diazonium ions (21) decomposed without participation of the double bond to give the (Z,E)-methoxycyclononadienes 22 and 23.The 21-derived carbene 29 afforded the bicyclic ether 30 and the elusive 1,2,4-cyclononatriene (32).In contrast to its lower homologs, 29 did not undergo a carbene-carbene rearrangement (29 -> 31).
