Check Digit Verification of cas no

The CAS Registry Mumber 155513-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,5,1 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 155513-83:
(8*1)+(7*5)+(6*5)+(5*5)+(4*1)+(3*3)+(2*8)+(1*3)=130
130 % 10 = 0
So 155513-83-0 is a valid CAS Registry Number.

Dihalogentriphenylphosphoranes in the synthesis of heterocycles, 29. A simple synthesis of pteridin-4-ones, from methyl-3-amino-2-pyrazinecarboxylate and pyrazino[3,1]oxazin-4-ones

Wamhoff,Kroth

, p. 405 - 410 (2007/10/02)

Methyl 3-amino-2-pyrazinecarboxylate (3) affords the synthetically useful 3-aroylaminopyrazin-2-carboxylates 5a-f with aroyl chlorides, which are converted with dibromotriphenylphosphorane into 2-arylpyrazino[2,3-d][3,1]oxazin-4-ones 6a-f. Nucleophilic attack at the carbonyl function of these oxazinones results in ring cleaved amides which can be recyclized with dibromotriphenylphosphorane to afford 2-arylpteridin-4-ones 7a-f.
