1307232-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1307232-50-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,7,2,3 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1307232-50:
(9*1)+(8*3)+(7*0)+(6*7)+(5*2)+(4*3)+(3*2)+(2*5)+(1*0)=113
113 % 10 = 3
So 1307232-50-3 is a valid CAS Registry Number.

Multicomponent synthesis of fused benzimidazolopiperazines
El Kaim, Laurent,Grimaud, Laurence,Reddy Purumandla, Srinivas
, p. 4728 - 4733 (2011)
We present a novel protocol for the efficient synthesis of fused benzimidazolo piperazines starting from a four-component Ugi-Smiles reaction and a subsequent three-step cascade involving an acid-catalyzed cyclization, an intramolecular reductive cyclizat
