Check Digit Verification of cas no

The CAS Registry Mumber 77178-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,7 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77178-42:
(7*7)+(6*7)+(5*1)+(4*7)+(3*8)+(2*4)+(1*2)=158
158 % 10 = 8
So 77178-42-8 is a valid CAS Registry Number.

PTERIDINES, LXX - SYNTHESIS AND PROPERTIES OF 1,8-ALKYLENE-BRIDGED LUMAZINES

Uhlmann, Eugen,Pfleiderer, Wolfgang

, p. 437 - 453 (2007/10/02)

A new type of lumazine derivatives (24-30) with a 1,8-alkylene bridge has been synthesized to study the protonation site in lumazine (1) itself.Comparisons of UV-data, however, do not allow a clear decision in this respect but indicate possibly the presence of a mixture of at least two cationic species.The structures of the newly synthesized compounds have been proven by UV- and NMR-spectra as well as pKa measurements and elementary analyses. 8-β-Hydroxyethyl-7-oxo-7,8-dihydrolumazines (15-17) show an easy cyclization to the corresponding 1,8-ethano-bridged derivatives 18-20 on boiling with DMF.
