Check Digit Verification of cas no

The CAS Registry Mumber 1440216-72-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,2,1 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1440216-72:
(9*1)+(8*4)+(7*4)+(6*0)+(5*2)+(4*1)+(3*6)+(2*7)+(1*2)=117
117 % 10 = 7
So 1440216-72-7 is a valid CAS Registry Number.

Rhodium-catalyzed [2+2+2] cycloaddition of oximes and diynes to give pyridines

Xu, Fen,Wang, Chunxiang,Wang, Dongping,Li, Xincheng,Wan, Boshun

, p. 2252 - 2255 (2013/03/28)

Oximes and diynes undergo efficient cycloaddition in the presence of a catalytic amount of a cationic rhodium(I)/dppf complex (see scheme). Spontaneous dehydration of the initially formed cycloadducts leads to the formation of a variety of substituted pyridines in moderate to good yields. The transformation could also be achieved in a one-pot procedure using aldehydes. Copyright
