38997-00-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 38997-00-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,9,9 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 38997-00:
(7*3)+(6*8)+(5*9)+(4*9)+(3*7)+(2*0)+(1*0)=171
171 % 10 = 1
So 38997-00-1 is a valid CAS Registry Number.

A General and Practicable Synthesis of Polycyclic Heteroaromatic Compounds. Part 2. Reaction of Quinone-methides of Pyridones, Pyrimidines, Coumarin, and Benzene with Aromatic Amines in a Novel Synthesis of Polycyclic Heteroaromatic Compounds

Asherson, Janet L.,Bilgic, Orhan,Young, Douglas W.

, p. 522 - 528 (2007/10/02)

The synthesis of polycyclic heteroaromatic compounds using the reaction of a quinone-methide, generated in situ, with an aromatic amine has been successfully extended using quinone-methides of coumarin and of pyridones.Preliminary studies with the benzenoid quinone-methide (33) have so far proved to give only low yields of the expected acridines.Generation of 'quinone-methides' in which the carbonyl is part of an amide group did not lead to polycyclic heteroaromatic compounds.
