Check Digit Verification of cas no

The CAS Registry Mumber 330624-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,6,2 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 330624-99:
(8*3)+(7*3)+(6*0)+(5*6)+(4*2)+(3*4)+(2*9)+(1*9)=122
122 % 10 = 2
So 330624-99-2 is a valid CAS Registry Number.

Synthesis of peptide di-aldehyde precursor for stepwise chemoselective ligations via oxime bonds

Lelièvre, Dominique,Buré, Corinne,Laot, Fabrice,Delmas, Agnès

, p. 235 - 238 (2001)

To synthezise a triple-function branched peptide in a modular way, we present a new strategy based on orthogonal generation of two aldehyde functions from an acetal and a 2-amino alcohol. Successive unmaskings of aldehyde functions of the stem peptide affords stepwise chemoselective ligations of two (aminooxy)acetyl peptides via oxime bonds.
