160291-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 160291-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,2,9 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 160291-50:
(8*1)+(7*6)+(6*0)+(5*2)+(4*9)+(3*1)+(2*5)+(1*0)=109
109 % 10 = 9
So 160291-50-9 is a valid CAS Registry Number.

Thiol-reactive Fluorescent probes for Protein Labelling
Corrie, John E. T.
, p. 2975 - 2982 (2007/10/02)
Cyclisation of N-alkylmaleic acids mediated by acetic anhydride in dimethylacetamide in the presence of traces of cobalt naphthenate has been used for efficient assembly of a range of fluorescent maleimide reagents.The fluorescence responses of these reagents to addition of thiol across the maleimide double bond, and to hydrolysis of the meleimide ring, are described.
