Check Digit Verification of cas no

The CAS Registry Mumber 1097643-39-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,7,6,4 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1097643-39:
(9*1)+(8*0)+(7*9)+(6*7)+(5*6)+(4*4)+(3*3)+(2*3)+(1*9)=184
184 % 10 = 4
So 1097643-39-4 is a valid CAS Registry Number.

Cyclophane-type imidazolium salts with planar chirality as a new class of N-heterocyclic carbene precursors

Matsuoka, Yuki,Ishida, Yasuhiro,Sasaki, Daisuke,Saigo, Kazuhiko

supporting information; experimental part, p. 9215 - 9222 (2009/10/01)

Cyclophane-type imidazolium salts with planar chirality were synthesized from enantiopure 2-amino alcohols, of which the N(1) and N(3) positions were connected with a bridge. The structural profiles of the imidazolium salts and their derivative N-heterocy
