Check Digit Verification of cas no

The CAS Registry Mumber 138853-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,5 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138853-82:
(8*1)+(7*3)+(6*8)+(5*8)+(4*5)+(3*3)+(2*8)+(1*2)=164
164 % 10 = 4
So 138853-82-4 is a valid CAS Registry Number.

A novel method for the specific glycosylation of proteins

Davis,Flitsch

, p. 6793 - 6796 (1991)

The N-acetyl-glucosamine derivative 1 was synthesised and reacted with peptides and proteins containing cysteine residues. Analysis of products by nmr and mass spectroscopy showed that the thiol groups of cysteine were selectively glycosylated via a new sugar-protein linkage (as in 2).
