Check Digit Verification of cas no

The CAS Registry Mumber 1266665-23-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,6,6,6 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1266665-23:
(9*1)+(8*2)+(7*6)+(6*6)+(5*6)+(4*6)+(3*5)+(2*2)+(1*3)=179
179 % 10 = 9
So 1266665-23-9 is a valid CAS Registry Number.

Bromopyridazinedione-mediated protein and peptide bioconjugation

Chudasama, Vijay,Smith, Mark E. B.,Schumacher, Felix F.,Papaioannou, Danai,Waksman, Gabriel,Baker, James R.,Caddick, Stephen

supporting information; experimental part, p. 8781 - 8783 (2011/09/16)

Bromopyridazinedione-mediated bioconjugation to a cysteine containing protein and a disulfide containing peptide is described. The conjugates are cleavable in an excess of thiol, including cytoplasmically-relevant concentrations of glutathione, and show a high level of hydrolytic stability. The constructs have the potential for four points of chemical attachment.
