1623792-00-6 Usage
Description
Bromo-PEG8-t-butyl ester is a PEG linker containing a bromide group and a t-butyl protected carboxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The t-butyl protected carboxyl group can be deprotected under acidic conditions.Check Digit Verification of cas no
The CAS Registry Mumber 1623792-00-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,3,7,9 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.Calculate Digit Verification of CAS Registry Number 1623792-00:
(9*1)+(8*6)+(7*2)+(6*3)+(5*7)+(4*9)+(3*2)+(2*0)+(1*0)=166
166 % 10 = 6
So 1623792-00-6 is a valid CAS Registry Number.
