Check Digit Verification of cas no

The CAS Registry Mumber 3054-37-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,5 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3054-37:
(6*3)+(5*0)+(4*5)+(3*4)+(2*3)+(1*7)=63
63 % 10 = 3
So 3054-37-3 is a valid CAS Registry Number.

Aminosaeuren, I. Darstellung von Aminosaeuren aus Halogencarbonsaeure-alkylestern mit Alkalimetallcyanaten

Effenberger, Franz,Drauz, Karlheinz,Foerster, Siegfried,Mueller, Wolfgang

, p. 173 - 189 (2007/10/02)

α- and ω-halo- as well as α,ω-dihalocarboxylic alkyl esters react with potassium cyanate in the presence of alcohol at 80 - 120 deg C in dipolar aprotic solvents to yield α- and ω-(alkoxycarbonylamino)- and α,ω-bis(alkoxycarbonylamino)carboxylic alkyl esters, respectively, in good yields.Hydrolytic cleavage of these mono- or diurethanes with an aqueous solution of hydrochloric acid/formic acid leads to the corresponding amino acid hydrochlorides in nearly quantitative yields.
