Check Digit Verification of cas no

The CAS Registry Mumber 180044-88-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,0,4 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 180044-88:
(8*1)+(7*8)+(6*0)+(5*0)+(4*4)+(3*4)+(2*8)+(1*8)=116
116 % 10 = 6
So 180044-88-6 is a valid CAS Registry Number.

Synthesis and Reactions of 2,2'-(m-Phenylene) Bis

Eltamany, E. H.,Osman, A.,Ibrahim, H. K.

, p. 381 - 392 (2007/10/03)

2,2'-(m-Phenylene)bis Va-d have been synthesized.The hydrolysis, alcoholysis, ammonolysis, aminolysis as well as hydrazinolysis of these oxazolones have been studied.When the products of alcoholysis, ammonolysis and aminolysis were heated above their melting points they have eliminated 2 molecules of alcohol. ammonia and amine respectively yielding the starting oxazolones.Also it was noted, that the alcoholysis may be catalyzed by sodium azide.The spectroscopic data by the newly synthesized compounds are discussed.Some of the newly synthesized compounds were tested to determine their dyeing and ...
