1019691-19-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1019691-19-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,9,6,9 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1019691-19:
(9*1)+(8*0)+(7*1)+(6*9)+(5*6)+(4*9)+(3*1)+(2*1)+(1*9)=150
150 % 10 = 0
So 1019691-19-0 is a valid CAS Registry Number.

Stereoretentive synthesis and chemoselective amide-forming ligations of C-terminal peptide α-ketoacids
Ju, Lei,Lippert, Alexander R.,Bode, Jeffrey W.
, p. 4253 - 4255 (2008)
C-Terminal peptide cyanosulfur ylides are readily converted to C-terminal peptide α-ketoacids, poised for chemoselective amide-forming reactions with hydroxylamines. These easily prepared and bench stable ylides are quickly and selectively oxidized with a
