S-acetyl-PEG2-t-butyl ester is a PEG (polyethylene glycol) linker that features a sulfur acetyl group and a t-butyl ester. This unique structure allows for the deprotection of the sulfur acetyl group to form a thiol group, while the t-butyl ester can be removed under acidic conditions. The hydrophilic PEG linker enhances the water solubility of compounds in aqueous media, making it a versatile molecule for various applications.

Check Digit Verification of cas no
The CAS Registry Mumber 1820641-93-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,8,2,0,6,4 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.Calculate Digit Verification of CAS Registry Number 1820641-93:
(9*1)+(8*8)+(7*2)+(6*0)+(5*6)+(4*4)+(3*1)+(2*9)+(1*3)=157
157 % 10 = 7
So 1820641-93-7 is a valid CAS Registry Number.
