Check Digit Verification of cas no

The CAS Registry Mumber 63546-88-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,5,4 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 63546-88:
(7*6)+(6*3)+(5*5)+(4*4)+(3*6)+(2*8)+(1*8)=143
143 % 10 = 3
So 63546-88-3 is a valid CAS Registry Number.

Electrochemical Conversion of Phthaldianilides to Phthalazin-1,4-diones by Dehydrogenative N?N Bond Formation

Kehl, Anton,Gieshoff, Tile,Schollmeyer, Dieter,Waldvogel, Siegfried R.

, p. 590 - 593 (2017/12/26)

The electrochemical synthesis of 6-membered rings via anodic dianilide N?N coupling is challenging due to concurring benzoxazole co-formation. The rigidity of the a phthalic acid backbone allows a novel access to phthalazin-1,4-diones by N?N bond formation using anodically generated amidyl radicals. Since conventional synthetic routes to phthalazin-1,4-diones require the use of toxic N,N′-diarylhydrazines and generate reagent waste, a safer and more sustainable approach is required. Easy accessible starting materials, a broad scope of applicable functional groups, promising yields, and a very simple set-up elevate this sustainable method.
