75681-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75681-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,8 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 75681-33:
(7*7)+(6*5)+(5*6)+(4*8)+(3*1)+(2*3)+(1*3)=153
153 % 10 = 3
So 75681-33-3 is a valid CAS Registry Number.

Synthesis of α-Keto Amides by a Pyrrolidine/TEMPO-Mediated Oxidation of α-Keto Amines
Yu, Lu,Somfai, Peter
, p. 2587 - 2590 (2016)
A mild procedure has been developed for the synthesis of α-keto amides by α-oxidation of the corresponding α-keto amines mediated by pyrrolidine and TEMPO. The method can also be applied to the synthesis of α-keto thioamides and α-keto amidines.
