Check Digit Verification of cas no

The CAS Registry Mumber 874097-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,0,9 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 874097-33:
(8*8)+(7*7)+(6*4)+(5*0)+(4*9)+(3*7)+(2*3)+(1*3)=203
203 % 10 = 3
So 874097-33-3 is a valid CAS Registry Number.

Synthesis and rotational barriers of atropisomers of 1,2-bis[5-(11H- benzo[b]fluorenyl)]benzenes and related compounds

Yang, Hua,Petersen, Jeffrey L.,Wang, Kung K.

, p. 1231 - 1238 (2007/10/03)

Several 1,2-bis[5-(11H-benzo[b]fluorenyl)]benzenes and related compounds were synthesized via a cascade reaction sequence of the corresponding benzannulated enyne-allene precursors. The X-ray structures showed that the two benzo[b]fluorenyl moieties attac
