Check Digit Verification of cas no

The CAS Registry Mumber 66548-93-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,5,4 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 66548-93:
(7*6)+(6*6)+(5*5)+(4*4)+(3*8)+(2*9)+(1*3)=164
164 % 10 = 4
So 66548-93-4 is a valid CAS Registry Number.

, p. 1284 - 1290 (2013/06/26)

A copper-catalyzed cascade dehydrogenative and dehalogenative reaction of halogenated 6-phenyl-4,5-dihydropyridazin-3(2H)-ones to 6-phenylpyridazin-3(2H)- ones has been developed. Moreover, the catalytic system consisting of copper(II) acetate/sodium carbonate/pyridine exhibits high reactivity and selectivity with oxygen as the terminal oxidant. Copyright
