Check Digit Verification of cas no

The CAS Registry Mumber 110623-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,6,2 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 110623-99:
(8*1)+(7*1)+(6*0)+(5*6)+(4*2)+(3*3)+(2*9)+(1*9)=89
89 % 10 = 9
So 110623-99-9 is a valid CAS Registry Number.

PHOTOLYSIS OF CYCLIC ACETALS OF ARYL BENZOYLACETATES AS THE KEY STEP IN A NEW SYNTHESIS OF FLAVONES

Garcia, Hermenegildo,Iborra, Sara,Miranda, Miguel A.,Primo, Jaime

, p. 2511 - 2517 (2007/10/02)

Although the yields found for the photo-Fries rearrangement of the aryl benzoylacetates 1 are poor, blocking of the carbonyl group, as in the related acetal derivatives 3, results in a substantial preparative improvement.Thus, the o-hydroxydibenzoylmethanes 2 are obtained from 1 with an average yield of 18percent, while the corresponding acetals 4 are obtained from 3 with an average yield of 58 percent.Compounds 4 are efficiently converted into flavones 8 by means of wet silica gel, through hydrolysis of the acetal moiety and subsequent cyclization of the resulting o-hydroxydibenzoylmethanes 2.
