1031685-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1031685-33-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,1,6,8 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1031685-33:
(9*1)+(8*0)+(7*3)+(6*1)+(5*6)+(4*8)+(3*5)+(2*3)+(1*3)=122
122 % 10 = 2
So 1031685-33-2 is a valid CAS Registry Number.

A Cu(I)-catalyzed C-H α-amination of esters. Direct synthesis of hydantoins
Zhao, Baoguo,Du, Haifeng,Shi, Yian
, p. 7220 - 7221 (2008/12/20)
This paper describes a novel intermolecular α-amination process of esters using CuCl as catalyst and di-tert-butyldiaziridinone as nitrogen source. A variety of hydantoins can be formed effectively under mild reaction conditions. Copyright
