Check Digit Verification of cas no

The CAS Registry Mumber 1273554-03-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,3,5,5 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1273554-03:
(9*1)+(8*2)+(7*7)+(6*3)+(5*5)+(4*5)+(3*4)+(2*0)+(1*3)=152
152 % 10 = 2
So 1273554-03-2 is a valid CAS Registry Number.

Chemistry of the enaminone of 1-acetylnaphthalene under microwave irradiation using chitosan as a green catalyst

Hassaneen, Huwaida M. E.

, p. 609 - 623 (2011/03/22)

Enaminone 1 was reacted with hydrazonoyl halides 2a-d to yield 3,4-disubstituted pyrazoles 6a-d. Coupling with arenediazonium chlorides afforded the 2-(arylhydrazono)-3-(1-naphthalenyl)-3-oxopropionaldehydes 13a-c. Compounds 13 could be utilized for the s
