The CAS Registry Mumber 171819-44-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,8,1 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 171819-44:
(8*1)+(7*7)+(6*1)+(5*8)+(4*1)+(3*9)+(2*4)+(1*4)=146
146 % 10 = 6

Reverse Cope Elimination Reactions. 1. Mechanism and Scope

Ciganek, Engelbert,Read, John M.,Calabrese, Joseph C.

, p. 5795 - 5802 (2007/10/03)

N-4-Pentenyl- and N-5-hexenyl-N-methylhydroxylamine cyclized under mild conditions in a reverse Cope elimination reaction to give 1,2-dimethylpyrrolidine N-oxide and 1,2-dimethylpiperidine N-oxide, respectively.The reaction was shown to be concerted and thermodynamically controlled.The scope of this novel cyclization is discussed, and comparisons are made with the closely related and previously reported cyclization of monosubstituted alkenylhydroxylamines to give cyclic hydroxylamines.
