Check Digit Verification of cas no

The CAS Registry Mumber 85471-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,4,7 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 85471-54:
(7*8)+(6*5)+(5*4)+(4*7)+(3*1)+(2*5)+(1*4)=151
151 % 10 = 1
So 85471-54-1 is a valid CAS Registry Number.

Conventional Synthesis of Thymopoietin 32-36 (TP 5) Using the 1-(1-Adamantyl)-1-methyletoxycarbonyl Group

Heinzel, Wolfgang,Kronbach, Thomas,Voelter, Wolfgang

, p. 1652 - 1658 (2007/10/02)

A synthesis of high yields of TP 5 is described.The α-amino functions were blocked by the acid-labile 1-(1-adamantyl)-1-methylethoxycarbonyl-(Adpoc)group.The Adpoc group is cleaved under mild acidolytic conditions with 3percent TFA in CH2Cl2 while the tert-butyl residues remained intact.This selective cleavage of the Adpoc group compared with the Boc and tert-butyl residues allows new strategies for the synthesis of large peptides. - Keywords: Adpoc, Amino acids, Thymopoietin
