731-66-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 731-66-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 731-66:
(5*7)+(4*3)+(3*1)+(2*6)+(1*6)=68
68 % 10 = 8
So 731-66-8 is a valid CAS Registry Number.

Studies in Synthesis of Xanthones: Part IV - Synthesis of Furanoxanthones

Patel, G. N.,Trivedi, K. N.

, p. 755 - 758 (2007/10/02)

The claisen migrations of 3-allyloxy-4-bromoxanthone and 3-allyloxy-4-iodoxanthone have been carried out in dimethylaniline, decalin and in vacuo to obtain different xanthones. 4-Bromofuranoxanthone (X) and 4-bromo-5'-methylfuranoxanthone (IX), have been synthesised from 2-allyl-3-hydroxy-4-bromoxanthone (VII).The structures of intermediates and final products have been confirmed by IR, mass and PMR spectral studies.
