Check Digit Verification of cas no

The CAS Registry Mumber 1450-92-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,5 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1450-92:
(6*1)+(5*4)+(4*5)+(3*0)+(2*9)+(1*2)=66
66 % 10 = 6
So 1450-92-6 is a valid CAS Registry Number.

Novel and efficient synthesis of 2-aminooxazoles from pyrimidin-2(1H)-one

Alifanov, Vadim L.,Babaev, Eugene V.

, p. 263 - 270 (2007/10/03)

Stepwise conversion of pyrimidin-2(1H)-one to 2-amino-5-aryloxazoles via oxazolo[3,2-a]pyrimidinium salts is reported. The sequence involves, (i) regioselective N-alkylation of pyrimidone by phenacyl bromides, (ii) cyclization of obtained 1-(2-aryl-2-oxoethyl)pyrimidin-2(1H)-ones into oxazolo[3,2-a] pyrimidinium salts under the action of fuming sulfuric (or triflic) acid, and (iii) reaction of the obtained salts with hydrazine leading to 2-amino-5-aryloxazoles.
