13638-71-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13638-71-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,3 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13638-71:
(7*1)+(6*3)+(5*6)+(4*3)+(3*8)+(2*7)+(1*1)=106
106 % 10 = 6
So 13638-71-6 is a valid CAS Registry Number.

Conformational Control in the 3,7-Diazabicyclononane System
McCabe, P. H.,Milne, N. J.,Sim, G. A.
, p. 625 - 626 (2007/10/02)
The twin-chair or boat-chair conformation of 3,7-diazabicyclononanes can be selected by forming N,N'-derivatives in which the N atoms have planar or pyramidal bonding patterns, respectively, e.g., acyl substituents for the former and arylsulphonyl
