General Description
H-Glu(Oall)-Oall p-Tosylate is a compound that consists of a glutamic acid derivative with two O-alllyloxycarbonyl protecting groups. It also has a p-tosylate functional group attached to the glutamic acid molecule. H-Glu(Oall)-Oall p-Tosylate is commonly used in peptide synthesis as a protecting group for the carboxyl group of glutamic acid, allowing for selective deprotection and further modification of the peptide chain. The p-tosylate group also serves as a leaving group during peptide bond formation. Overall, H-Glu(Oall)-Oall p-Tosylate plays a crucial role in the efficient and controlled assembly of peptides in chemical synthesis.Check Digit Verification of cas no
The CAS Registry Mumber 20845-16-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,4 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.Calculate Digit Verification of CAS Registry Number 20845-16:
(7*2)+(6*0)+(5*8)+(4*4)+(3*5)+(2*1)+(1*6)=93
93 % 10 = 3
So 20845-16-3 is a valid CAS Registry Number.
