Check Digit Verification of cas no

The CAS Registry Mumber 29043-09-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,0,4 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 29043-09:
(7*2)+(6*9)+(5*0)+(4*4)+(3*3)+(2*0)+(1*9)=102
102 % 10 = 2
So 29043-09-2 is a valid CAS Registry Number.

STUDIES OF THE SELECTIVE O-ALKYLATION AND DEALKYLATION OF FLAVONOIDS. XII. A NEW, CONVENIENT METHOD FOR SYNTHESIZING 3,5-DIHYDROXY-6,7-DIMETHOXYFLAVONES FROM 3,5,6,7-TETRAMETHOXYFLAVONES

The 5-methoxy group on 3,5,6,7-tetramethoxyflavones and the 3-methoxy group on 3,6,7-trimethoxy-5-tosyloxy-flavones were selectively cleaved with anhydrous aluminum bromide in acetonitrile under controlled conditions without the cleavage of benzyloxy groups on the B ring.By the application of these reactions, seven 3,5-dihydroxy-6,7-dimethoxyflavones were easily synthesized from the corresponding 3,5,6,7-tetramethoxyflavones which were synthesized from 3,6-dihydroxy-2,4ω-trimethoxycetophenone by means of the Allan-Robinson reaction followed by methylation.Keywords: Allan-Robinson reaction ; selective demethylation; 3,5,6,7-tetramethoxyflavone; 5-hydroxy-3,6,7-trimethoxyflavone; 6-hydroxy-3,5,7-trimethoxyflavone; 5-tosyloxyflavone; 5,6-dihydroxy-3,7-dimethoxyflavone; 3,5-dihydroxy-6,7-dimethoxyflavone, 3,5-diacetoxy-6,7-dimethoxyflavone
