Check Digit Verification of cas no

The CAS Registry Mumber 1403502-87-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,5,0 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1403502-87:
(9*1)+(8*4)+(7*0)+(6*3)+(5*5)+(4*0)+(3*2)+(2*8)+(1*7)=113
113 % 10 = 3
So 1403502-87-3 is a valid CAS Registry Number.

Planar-chiral [7]orthocyclophanes

Tomooka, Katsuhiko,Uehara, Kazuhiro,Igawa, Kazunobu,Iso, Chisato,Suzuki, Masaki,Nishikawa-Shimono, Rie

, p. 10355 - 10358,4 (2020/09/15)

Just plain chiral: The [7]orthocyclophanes 1, having an E-olefinic ansa chain, exhibit planar chirality at ambient temperature and their stereochemical stabilities are highly dependent upon the embedded X group in the ansa chain. Inter- and intramolecular transformations of 1 (where X=NTs) provide a variety of nitrogen-containing chiral molecules in a stereospecific manner. Ts=4-toluenesulfonyl. Copyright
