92012-31-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92012-31-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,0,1 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 92012-31:
(7*9)+(6*2)+(5*0)+(4*1)+(3*2)+(2*3)+(1*1)=92
92 % 10 = 2
So 92012-31-2 is a valid CAS Registry Number.

Catalytic Hydrogenation of Pyrroles at Atmospheric Pressure
Kaiser, Hans-Peter,Muchowski, Joseph M.
, p. 4203 - 4209 (2007/10/02)
N-(tert-Butoxycarbonyl)pyrroles are catalytically hydrogenated to the corresponding pyrrolidines, over 5percent platinum on carbon catalyst, at room temperature and atmospheric pressure.Under these conditions O-benzyl groups are retained and 2,5-disubstit
