Check Digit Verification of cas no

The CAS Registry Mumber 105551-35-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,5,5 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105551-35:
(8*1)+(7*0)+(6*5)+(5*5)+(4*5)+(3*1)+(2*3)+(1*5)=97
97 % 10 = 7
So 105551-35-7 is a valid CAS Registry Number.

PHOTOREARRANGEMENT OF 3-ARYLOXYANTHRA-6-ISOXAZOLONES TO NAPHTHOPHENOXAZINE-8,13-DIONES

Dmitriev, F. M.,Gornostaev, L. M.,Gritsan, N. P.,El'tsov, A. V.

, p. 2243 - 2251 (2007/10/02)

3-Aryloxyanthra-6-isoxazolones gives good chemical and quantum yields of the photorearrangement products naphthophenoxazine-8,13-diones, identical with the thermal rearrangement products.The formation of a spiro intermediate was demonstrated.An intermediate particle which changes thermally into the final reaction product was detected.The structure of the intermediate particle was determined by study of the photochemical and subsequent thermal transformations of 3-(2,4,6-trimethylphenoxy)-5-hydroxyanthra-6-isoxazolone.Slow conversion at the nitrogen atom was detected in N-methyl-1,3-dimethylnaphtho phenoxazine-8,13-dione
