146803-37-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146803-37-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,8,0 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 146803-37:
(8*1)+(7*4)+(6*6)+(5*8)+(4*0)+(3*3)+(2*3)+(1*7)=134
134 % 10 = 4
So 146803-37-4 is a valid CAS Registry Number.

Facile peptide thioester synthesis via solution-phase tosylamide preparation
Manabe, Shino,Sugioka, Tomoyuki,Ito, Yukishige
, p. 849 - 853 (2007/10/03)
Preparation of peptide thioester is essential for native chemical ligation and block condensation. Our novel methodology involves conversion of the carboxylic acid of a peptide into a thioester using p-toluenesulfonyl isocyanate, followed by alkylation, t
