Check Digit Verification of cas no

The CAS Registry Mumber 1401421-36-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,1,4,2 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1401421-36:
(9*1)+(8*4)+(7*0)+(6*1)+(5*4)+(4*2)+(3*1)+(2*3)+(1*6)=90
90 % 10 = 0
So 1401421-36-0 is a valid CAS Registry Number.

Copper-catalyzed aerobic dehydrogenative cyclization of N-methyl-N-phenylhydrazones: Synthesis of cinnolines

Zhang, Guangwu,Miao, Jinmin,Zhao, Yan,Ge, Haibo

supporting information; experimental part, p. 8318 - 8321 (2012/09/07)

O2 leading the way: The title reaction proceeds through an oxidation/cyclization sequence, thus representing the first copper-catalyzed coupling reaction of hydrazones through a C sp 3-H bond functionalization process (see scheme; DMF=N,N'-dimethylformamide, Py=pyridine). The method provides an environmentally friendly and atom-efficient approach to biologically active cinnoline derivatives. Copyright
