Check Digit Verification of cas no

The CAS Registry Mumber 209394-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,3,9 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 209394-99:
(8*2)+(7*0)+(6*9)+(5*3)+(4*9)+(3*4)+(2*9)+(1*9)=160
160 % 10 = 0
So 209394-99-0 is a valid CAS Registry Number.

A triple layered helical chiral cyclophane-one-pot synthesis, enantiomer separation and chiroptical properties

Harren, Joerg,Sobanski, Adam,Nieger, Martin,Yamamoto, Chiyo,Okamoto, Yoshio,Voegtle, Fritz

, p. 1369 - 1375 (1998)

The triple layered tetraazacyclophane 3a was prepared in high yield by a fourfold bond connection in a one-pot reaction sequence. The helical chirality of 3a results from the unique crossed meta/meta-cyclophane linkage. A racemisation process can only tak
