Check Digit Verification of cas no

The CAS Registry Mumber 89004-90-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,0 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89004-90:
(7*8)+(6*9)+(5*0)+(4*0)+(3*4)+(2*9)+(1*0)=140
140 % 10 = 0
So 89004-90-0 is a valid CAS Registry Number.

Syntheses and Properties of Dimethyldiphenyltetradehydro-trideca-, -pentadeca-, -heptadeca-, -nonadeca-fulvene, and Benzannelated Pentadecafulvene Derivatives

Kuroda, Shigeyasu,Ojima, Juro,Kitatani, Kazuto,Kirita, Mitsuru,Nakada, Tadayuki

, p. 2987 - 2996 (2007/10/02)

Syntheses of 4,9-dimethyl-13-diphenylmethylene-5,6,7,8-tetradehydrocyclotridecene (7), 4,9-dimethyl-15-diphenylmethylene-5,6,7,8-tetradehydrocyclopentadecene (8), 6,11-dimethyl-17-diphenylmethylene-7,8,9,10-tetradehydrocyclopentadecene (9), and 6,11-dimethyl-19-diphenylmethylene-7,8,9,10-tetradehydrocyclononadecene (10) are described.Although examination of the 1H n.m.r. spectra suggested that all of the fulvenes (7)-(10) are atropic, the benzannelated derivatives of pentadecafulvene (8), i.e. 13-methyl-7-diphenylmethylene-14,15,16,17-tetradehydrobenzocyclopentadecene (25), 13-methyl-9-diphenylmethylene-14,15,16,17-tetradehydrobenzocyclopentadecene (26) and 7-diphenylmethylene-16,17,18,19-tetradehydrodibenzocyclopentadecene (27) were prepared in order to examine the tropicity of (8) more closely.Comparison of the 1H n.m.r. spectra of these benzannelated fulvenes (25)-(27) with that of 88) reveals that the nonbenzannelated fulvene 88) is atropic.The influence of benzannelation upon the structure of the molecular skeleton of the tetradehydropentadecafulvene system is also discussed.

SYNTHESES AND PROPERTIES OF BENZANNELATED DIPHENYLPENTADECAFULVENE DERIVATIVES

Ojima, Juro,Kuroda, Shigeyasu,Kirita, Mitsuru

, p. 1371 - 1374 (2007/10/02)

Synthesis of 10-methyl-16,16-diphenyl-4,5-benzo-6,8-bisdehydro- 4, 12-methyl-16,16-diphenyl-6,7-benzo-8,10-bisdehydro- 5, and 16,16-diphenyl-4,5:10,11-dibenzo-6,8-bisdehydropentadecafulvene 6, has been described.Comparison of 1H-NMR spectra of these benzannelated fulvenes 4-6 with that of nonbenzannelated fulvene 3 reveals that 5,10-dimethyl-16,16-diphenyl-6,8-bisdehydropentadecafulvene 3 is atropic.
