65680-53-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65680-53-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,6,8 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 65680-53:
(7*6)+(6*5)+(5*6)+(4*8)+(3*0)+(2*5)+(1*3)=147
147 % 10 = 7
So 65680-53-7 is a valid CAS Registry Number.

Preparation of Nonsymmetrical p-Benzoquinone Diimines for Evaluation as Protein Cleavage Reagents
Holmes, Thomas J.,Lawton, Richard G.
, p. 3146 - 3150 (1983)
In an effort to improve the yield, selectivity, and mildness of reaction conditions employed in protein cleavage with bisalkylating quinone diimines, a series of analogous reagents (1a-h) were prepared.These novel N1,N4 nonsymmetrica
