112253-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112253-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,2,5 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 112253-40:
(8*1)+(7*1)+(6*2)+(5*2)+(4*5)+(3*3)+(2*4)+(1*0)=74
74 % 10 = 4
So 112253-40-4 is a valid CAS Registry Number.

A Novel Two-Step Synthesis of Hexahydropyrazinoquinolines
Nijhuis, Walter H. N.,Verboom, Willem,Reinhoudt, David N.
, p. 641 - 645 (2007/10/02)
The hexahydropyrazinoquinolines 2 were prepared in good yields by reaction of 2-(4-substituted 1-piperazinyl)benzaldehydes 5 with malononitrile and subsequent thermal cyclization of the condensation products 6; the latter reaction takes place via a
