452282-29-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 452282-29-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,2,2,8 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 452282-29:
(8*4)+(7*5)+(6*2)+(5*2)+(4*8)+(3*2)+(2*2)+(1*9)=140
140 % 10 = 0
So 452282-29-0 is a valid CAS Registry Number.

A facile stereospecific synthesis of α-hydrazino esters
Oguz, Umut,Guilbeau, Garett G.,McLaughlin, Mark L.
, p. 2873 - 2875 (2007/10/03)
A convenient route to make α-hydrazino esters from their corresponding α-amino esters is reported. A key step is selective nitrosamine reduction using activated Zn, conc. HCl, and methanol at low temperatures giving nearly quantitative yields of the pure α-hydrazino esters.
