Check Digit Verification of cas no

The CAS Registry Mumber 13476-24-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,7 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13476-24:
(7*1)+(6*3)+(5*4)+(4*7)+(3*6)+(2*2)+(1*4)=99
99 % 10 = 9
So 13476-24-9 is a valid CAS Registry Number.

A New Synthesis of Alloptaeroxylin, Its Methyl Ether and Related Compounds

Prasad, K. J. Rajendra,Iyer, P. R.

, p. 570 - 571 (2007/10/02)

Claisen condensation of 6-acetyl-5,7-dihydroxy-2,2-dimethylchroman (I) with sodium and ethyl acetate gives isoheteropeucenin (II) and isopeucenin (III).Benzylic bromination of II and III with NBS followed by dehydrobromination with pyridine affords alloptaeroxylin (IV) and dehydroisopeucenin (V) respectively.IV on methylation gives alloptaeroxylin methyl ether (VI).VI has also been synthesized by an alternate route.
