Check Digit Verification of cas no

The CAS Registry Mumber 640266-23-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,6 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 640266-23:
(8*6)+(7*4)+(6*0)+(5*2)+(4*6)+(3*6)+(2*2)+(1*3)=135
135 % 10 = 5
So 640266-23-5 is a valid CAS Registry Number.

Effect of Copper Salts on Peptide Bond Formation Using Peptide Thioesters

Ingenito, Raffaele,Wenschuh, Holger

, p. 4587 - 4590 (2003)

(Matrix presented) In the present paper, systematic studies revealed that Cu(I) salts in general and Cu(II) salts under certain circumstances promote effective reaction between peptide thiol esters and the N-terminal amino function of a second peptide seg
