137300-55-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137300-55-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,0 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137300-55:
(8*1)+(7*3)+(6*7)+(5*3)+(4*0)+(3*0)+(2*5)+(1*5)=101
101 % 10 = 1
So 137300-55-1 is a valid CAS Registry Number.

meso-2,5-Dimercapto-N,N,N',N'-tetramethyladipamide: A Readily Available, Kinetically Rapid Reagent for the Reduction of Disulfides in Aqueous Solution

Lees, Watson J.,Singh, Rajeeva,Whitesides, George M.

, p. 7328 - 7331 (1991)

meso-2,5-Dimercapto-N,N,N',N'-tetramethyladipamide (meso-DTA) reduces disulfide bonds up to 8 times faster (kinetic) than does dithiothreitol (DTT) in aqueous solution at pH 7.0. meso-DTA is easily synthesized in five steps (39percent overall yield) from adipic acid. meso-DTA, which forms a cyclic disulfide, is less reducing than DTT by approximately 56 mV, but is much more reducing than mercaptoethanol.
