1951439-37-4 Usage
Description
Bromo-PEG4-azide is a bifunctional crosslinker containing a bromide and a terminal azide. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a good leaving group for nucleophilic substitution. The azide(N3) group is reactive with alkyne, BCN, DBCO via Click Chemistry.Check Digit Verification of cas no
The CAS Registry Mumber 1951439-37-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,9,5,1,4,3 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.Calculate Digit Verification of CAS Registry Number 1951439-37:
(9*1)+(8*9)+(7*5)+(6*1)+(5*4)+(4*3)+(3*9)+(2*3)+(1*7)=194
194 % 10 = 4
So 1951439-37-4 is a valid CAS Registry Number.
