75910-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75910-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,1 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75910-49:
(7*7)+(6*5)+(5*9)+(4*1)+(3*0)+(2*4)+(1*9)=145
145 % 10 = 5
So 75910-49-5 is a valid CAS Registry Number.

Reactions of &α,&β-Unsaturated &γ-Oxosulfones with Nucleophiles
Messinger, Paul,Greve, Harald
, p. 688 - 696 (2007/10/02)
Bromination of the γ-oxosulfones 1 and subsequent dehydrohalogenation leads to the α,β-unsaturated γ-oxosulfones 3.These products react with primary and secondary amines to yield the enaminoketones 7. γ-Oxobissulfones 10 are formed from 3 by addition of t
