Check Digit Verification of cas no
The CAS Registry Mumber 331633-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,6,3 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 331633-97:
(8*3)+(7*3)+(6*1)+(5*6)+(4*3)+(3*3)+(2*9)+(1*7)=127
127 % 10 = 7
So 331633-97-7 is a valid CAS Registry Number.

Chemoselective elaboration of O-linked glycopeptide mimetics by alkylation of 3-thioGalNAc
Marcaurelle,Bertozzi
, p. 1587 - 1595 (2007/10/03)
A critical branch point in mucin-type oligosaccharides is the β1 → 3 glycosidic linkage to the core α-N-acetylgalactosamine (GalNAc) residue. We report here a strategy for the synthesis of O-linked glycopeptide analogues that replaces this linkage with a
