131172-76-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131172-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,7 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131172-76:
(8*1)+(7*3)+(6*1)+(5*1)+(4*7)+(3*2)+(2*7)+(1*6)=94
94 % 10 = 4
So 131172-76-4 is a valid CAS Registry Number.

CATALYTIC HYDROGENATION OF PYRIDINIUM SALTS
Reshetov, P. V.,Rozhnova, S. A.,Kriven'ko, A. P.
, p. 60 - 63 (1994)
Catalytic hydrogenation of polysubstituted pyridinium salts leads to piperidines and their condensed analogs.The spatial properties and conformational properties of the saturated azaheterocycles have been determined by 13C NMR spectroscopy.It was shown th
