511521-54-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 511521-54-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,1,5,2 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 511521-54:
(8*5)+(7*1)+(6*1)+(5*5)+(4*2)+(3*1)+(2*5)+(1*4)=103
103 % 10 = 3
So 511521-54-3 is a valid CAS Registry Number.

, p. 2645 - 2651 (2007/10/03)
A simple and versatile method for the enantio- and diastereoselective synthesis of mono- or disubstituted 3-aminoazepanes is described. The key step involves a highly regio- and diastereoselective tandem ring-enlargement/alkylation or reduction process. T
