1807539-07-6 Usage
Description
Benzyl-PEG6-Ms is a PEG linker containing a benzyl protecting group and a mesyl group. The benzyl moiety can be used as an alcohol protecting group and can be removed via hydrogenolysis. The mesyl group is a good leaving group for substitution reactions. The hydrophilic PEG linkers increase the water solubility of the compound in aqueous media. The water solubility properties of the PEG linker are enhanced with longer PEG chains.
Check Digit Verification of cas no
The CAS Registry Mumber 1807539-07-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,8,0,7,5,3 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1807539-07:
(9*1)+(8*8)+(7*0)+(6*7)+(5*5)+(4*3)+(3*9)+(2*0)+(1*7)=186
186 % 10 = 6
So 1807539-07-6 is a valid CAS Registry Number.
