511302-28-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 511302-28-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,1,3,0 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 511302-28:
(8*5)+(7*1)+(6*1)+(5*3)+(4*0)+(3*2)+(2*2)+(1*8)=86
86 % 10 = 6
So 511302-28-6 is a valid CAS Registry Number.

Hypervalent iodine catalyzed hofmann rearrangement of carboxamides using oxone as terminal oxidant

Yoshimura, Akira,Middleton, Kyle R.,Luedtke, Matthew W.,Zhu, Chenjie,Zhdankin, Viktor V.

, p. 11399 - 11404 (2013/02/23)

Hofmann rearrangement of carboxamides to carbamates using Oxone as an oxidant can be efficiently catalyzed by iodobenzene. This reaction involves hypervalent iodine species generated in situ from catalytic amount of PhI and Oxone in the presence of 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) in aqueous methanol solutions. Under these conditions, Hofmann rearrangement of various carboxamides affords corresponding carbamates in high yields.
