Check Digit Verification of cas no

The CAS Registry Mumber 5777-88-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,7 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5777-88:
(6*5)+(5*7)+(4*7)+(3*7)+(2*8)+(1*8)=138
138 % 10 = 8
So 5777-88-8 is a valid CAS Registry Number.

One-pot synthesis of phthalazines and pyridazino-aromatics: A novel strategy for substituted naphthalenes

Kessler, Simon N.,Wegner, Hermann A.

supporting information; experimental part, p. 3268 - 3271 (2012/08/28)

A new one-pot strategy for the synthesis of phthalazines and pyridazino-aromatics starting from aromatic aldehydes has been developed. A variety of substituents ranging from electron withdrawing to donating is tolerated furnishing the desired 1,2-diazine in good to excellent yields. The products have been applied to the bidentate Lewis acid catalyzed inverse electron-demand Diels-Alder (IEDDA) reaction opening a novel two-step entry into substituted naphthalenes, such as Naproxen.
