131244-21-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131244-21-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,2,4 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131244-21:
(8*1)+(7*3)+(6*1)+(5*2)+(4*4)+(3*4)+(2*2)+(1*1)=78
78 % 10 = 8
So 131244-21-8 is a valid CAS Registry Number.

Stereoselective Synthesis of (+/-)-cis-Inos-1,3-diamines
Beier, Barbara,Schuerrle, Karsten,Werbitzky, Oleg,Piepersberg, Wolfgang
, p. 2255 - 2262 (2007/10/02)
This contribution presents stereoselective routes to various cis-inos-1,3-diamines starting from readily available cis-4-aminocyclohexenols (7) and (8).The second nitrogen function is introduced into the ring by use of intramolecular cyclisations of neigh
