116776-68-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116776-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,7,7 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 116776-68:
(8*1)+(7*1)+(6*6)+(5*7)+(4*7)+(3*6)+(2*6)+(1*8)=152
152 % 10 = 2
So 116776-68-2 is a valid CAS Registry Number.

A New Synthetic Route to 4,6-Diarylpyridazinones and Some of their Derivatives
Coudert, P.,Couquelet, J.,Tronche, P.
, p. 799 - 802 (2007/10/02)
A novel approach to the titled ring system starting from conveniently available chalcones 1 is proposed.It involves a catalysed exchange of hydrogen cyanide between acetone cyanohydrin and 1.The resulting γ-ketonitriles 2 give the expected 4,6-diarylpyrid
