Check Digit Verification of cas no
The CAS Registry Mumber 1665-84-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,6 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1665-84:
(6*1)+(5*6)+(4*6)+(3*5)+(2*8)+(1*4)=95
95 % 10 = 5
So 1665-84-5 is a valid CAS Registry Number.

Copper-Catalyzed aerobic intramolecular dehydrogenative cyclization of n,n-disubstituted hydrazones through C sp 3 -H functionalization
Zhang, Guangwu,Zhao, Yan,Ge, Haibo
, p. 2559 - 2563 (2013/04/10)
An aerobic activity: The title reaction proceeds through an oxidation/cyclization/aromatization sequence under an atmosphere of O 2 (see scheme; DBU=1,8-diazabicyclo[5.4.0]undec-7-ene, DCE=1,2-dichloroethane, DMS=dimethylsulfide). This coupling
