922517-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 922517-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,2,5,1 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 922517-77:
(8*9)+(7*2)+(6*2)+(5*5)+(4*1)+(3*7)+(2*7)+(1*7)=169
169 % 10 = 9
So 922517-77-9 is a valid CAS Registry Number.

Staudinger ligation of peptides at non-glycyl residues
Soellner, Matthew B.,Tam, Annie,Raines, Ronald T.
, p. 9824 - 9830 (2007/10/03)
The Staudinger ligation provides a means to form an amide bond between a phosphinothioester and azide. This reaction holds promise for the ligation of peptides en route to the total chemical synthesis of proteins. (Diphenylphosphino)methanethiol is the mo
