Check Digit Verification of cas no

The CAS Registry Mumber 219829-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,8,2 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 219829-93:
(8*2)+(7*1)+(6*9)+(5*8)+(4*2)+(3*9)+(2*9)+(1*3)=173
173 % 10 = 3
So 219829-93-3 is a valid CAS Registry Number.

Stereoselective synthesis of α-C-glucosamines via anomeric organosamarium reagents

Andersen, Lise,Mikkelsen, Lise Munch,Beau, Jean-Marie,Skrydstrup, Troels

, p. 1393 - 1395 (1998)

The direct coupling of the pyridyl sulfone of N-acetylglucosamine with aldehydes or ketones is promoted by samarium diiodide affording the corresponding α-C-glycosides preferentially. A C-disaccharide has been synthesized using this approach.
