Check Digit Verification of cas no

The CAS Registry Mumber 791-34-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,9 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 791-34:
(5*7)+(4*9)+(3*1)+(2*3)+(1*4)=84
84 % 10 = 4
So 791-34-4 is a valid CAS Registry Number.

REACTIONS OF CYCLIC ANHYDRIDES XVI. A NOVEL APPROACH TO ANGULAR OXYGENATED PYRROLOBENZOXAZINONES

Balasubramaniyan, V.,Argade, N. P.

, p. 835 - 842 (2007/10/02)

o-Carboxymaleanilic acids IIIa-g when treated with sodium acetate-acetic anhydride underwent double cyclisation leading to pyrrolobenzoxazinones Va-g carrying an angular acetate.A one-flask reaction of dimethylmaleic anhydride and phthalic anhydride with anthranilic acid furnished the angular hydroxy benzoxazinones IVh and IVi respectively, which were converted to the corresponding acetates Vh and Vi.The acetates Va, Vc, Vf, Vg and Vi underwent solvolysis to the corresponding methyl ethers (VII) on refluxing with anhydrous methanol.
