Check Digit Verification of cas no

The CAS Registry Mumber 204503-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,5,0 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 204503-55:
(8*2)+(7*0)+(6*4)+(5*5)+(4*0)+(3*3)+(2*5)+(1*5)=89
89 % 10 = 9
So 204503-55-9 is a valid CAS Registry Number.

Synthesis of some new pyrimidines, thienopyrimidines and thiopyranopyrimidines

Assy,Amer,El-Bahaie,Halima

, p. 61 - 65 (2007/10/03)

Isothiocyanate 1 reacted with enaminone 2 to give thioamide 3 that cyclized by sodium hydroxide to pyrimidine 4 but cyclized by bromine to give isothiazole 5, pyrimidine 4 was transformed into thiopyranopyrimidines 7, 9 or 11 upon respective reaction with benzaldehyde, maleic acid, or maleic anhydride. Aminative cyclization of 4 yielded isothiazolopyrimidine 13. Reaction of 4 and ethyl bromoacetate or phenacyl bromides afforded thienopyrimidines 15a-b respectively. Oxidation of 4 yielded oxopyrimidine 16.
