Check Digit Verification of cas no
The CAS Registry Mumber 99747-54-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,4 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 99747-54:
(7*9)+(6*9)+(5*7)+(4*4)+(3*7)+(2*5)+(1*4)=203
203 % 10 = 3
So 99747-54-3 is a valid CAS Registry Number.

A facile synthesis of pyrrolo-[3,2-d]pyrimidines from 6-azidouracils and ylide phosphoranes

, p. 357 - 365 (2007/10/03)
A series of the title compounds, 9-deazaxanthines, was regioselectively prepared in reasonable yields as major products from the reactions of 6-azidouracils 1a,b with stabilized ester-2a,b or keto-2c ylide phosphoranes and a moderated phosphorus ylide 3, instead of the expected triazoles. Side products were also observed wherein pyrimido[5,4-g]pteridine-2,4,5,7-tetrone (15) and other fused ring systems or acyclic-substituted uracil derivatives were isolated. A comparative study on the reactivity of 1a in analogy to 1b toward phosphoranes is also described.
Reactions of Uracils. 6. New Ring Transformations of 6-Aminouracils with Acetylenedicarboxylates to Pyridinedionates and Pyrrolopyridines. Some Revised Constitutions

Treatment of 6--1,3-dimethyluracils 8 with dialkyl acetylenedicarboxylates in aprotic solvents affords zwitterionic pyridinedionates 12, involving a novel ring transformation reaction, via cleaving attack of a terminal carbanion to the 2-carbonyl of the uracil.In protic solvents 12 undergo a smooth heterocyclization reaction to give the pyrrolopyridines 14.The structures of 12b and 14b have been established by single-crystal X-ray diffraction.By spectroscopic comparison as well as by independent syntheses 12 proved to be closely related (phosphorylated) analogues of previously reported "ureas 17 and 18", while 13 was identical with the "5-propynoyluracil 15".Catalytic hydrogenation of 13a gave carbinol 20, which proved by means of 1H (H-D exchange) and 13C NMR to be identical with "cis-olefin 19".
