123845-24-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123845-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,4 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123845-24:
(8*1)+(7*2)+(6*3)+(5*8)+(4*4)+(3*5)+(2*2)+(1*4)=119
119 % 10 = 9
So 123845-24-9 is a valid CAS Registry Number.

STRATEGY FOR THE SYNTHESIS OF UNSYMMETRICAL N-SUBSTITUTED POLYAZAMACROCYCLES
Gu, Kunjian,Mertes, Kristin Bowman,Mertes, Mathias P.
, p. 1323 - 1326 (2007/10/02)
A covergent route is described for the preparation of unsymmetrical N-substituted polyammonium macrocycles that is potentially applicable for the synthesis of a wide variety of macrocycles of differing ring size and heteroatom substitution.
