Check Digit Verification of cas no

The CAS Registry Mumber 6815-33-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,1 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6815-33:
(6*6)+(5*8)+(4*1)+(3*5)+(2*3)+(1*3)=104
104 % 10 = 4
So 6815-33-4 is a valid CAS Registry Number.

DDQ Oxidation of 6- or 8-Allyl-7-hydroxycoumarins. A New Synthesis of Benzodipyrandiones and Furobenzopyranones

Prashant, Avula,Krupadanam, Gazula Levi David,Srimannarayana, Gutely

, p. 1191 - 1193 (2007/10/02)

A novel synthesis of 2H,8H-benzodipyran-2,8-diones, 2H,8H-benzodipyran-2,8-diones, 2H-furobenzopyran-2-ones, and 7H-furobenzopyran-7-ones was achieved by developing 2-pyrone and furan ring over coumarin. 6- or 8-Allyl-7-hydroxycoumarins on oxidation with 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) afforded benzodipyrandiones and furobenzopyranones.The structures of the compounds now synthesized were established by analytical, spectral, and comparison with authentic samples prepared by the known procedures.
