827624-89-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 827624-89-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,7,6,2 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 827624-89:
(8*8)+(7*2)+(6*7)+(5*6)+(4*2)+(3*4)+(2*8)+(1*9)=195
195 % 10 = 5
So 827624-89-5 is a valid CAS Registry Number.

, p. 849 - 853 (2007)
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
