128375-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128375-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,3,7 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128375-93:
(8*1)+(7*2)+(6*8)+(5*3)+(4*7)+(3*5)+(2*9)+(1*3)=149
149 % 10 = 9
So 128375-93-9 is a valid CAS Registry Number.

Synthesis of a Troger's Base Analogue via Stereoselective Reductive Coupling of N-Phenylpiperazine to Norbornane-2,5-dione
Katz, H. E.
, p. 126 - 127 (2007/10/02)
The reaction of N-phenylpiperazines with norbornane-2,5-dione and NaCNBH3 gives the endo-endo dipiperazinyl norbornanes, which define a right triangular cavity potentially useful in host-guest chemistry as determined by X-ray crystallography and dipole mo
