1255466-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1255466-49-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,5,4,6 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1255466-49:
(9*1)+(8*2)+(7*5)+(6*5)+(5*4)+(4*6)+(3*6)+(2*4)+(1*9)=169
169 % 10 = 9
So 1255466-49-9 is a valid CAS Registry Number.

Traceless ligation of cysteine peptides using selective deselenization
Metanis, Norman,Keinan, Ehud,Dawson, Philip E.
, p. 7049 - 7053 (2010)
Selective deselenization: Native chemical ligation at selenocysteine is followed by selective deselenization of the selenocysteine to alanine, in the presence of cysteine residues without protecting groups (see scheme). This selectivity is achieved by usi
