71649-29-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71649-29-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,4 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71649-29:
(7*7)+(6*1)+(5*6)+(4*4)+(3*9)+(2*2)+(1*9)=141
141 % 10 = 1
So 71649-29-1 is a valid CAS Registry Number.

Process for preparing 2-methyl-2-hydroxypropyl piperazine-1-carboxylate compounds
-
, (2008/06/13)
Isobutylene carbonate and certain 1-substituted piperazine compounds are reacted in a process that forms 2-methyl-2-hydroxypropyl 4-substituted piperazine-1-carboxylate compounds which are medicinal agents or synthetic intermediates for such agents. The features of the process allow the preparation of an essentially pure 2-methyl-2-hydroxypropyl carboxylate compound.
