Check Digit Verification of cas no

The CAS Registry Mumber 643768-32-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,3,7,6 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 643768-32:
(8*6)+(7*4)+(6*3)+(5*7)+(4*6)+(3*8)+(2*3)+(1*2)=185
185 % 10 = 5
So 643768-32-5 is a valid CAS Registry Number.

Synthesis of new enantiomerically pure C1- and C 2-symmetric N-alkyl-benzimidazolium and thiazolium salts

Orlandi, Simonetta,Caporale, Marinella,Benaglia, Maurizio,Annunziata, Rita

, p. 3827 - 3830 (2003)

Starting from the commercially available enantiopure (1S,2S)-2-amino-1- phenyl-1,3-propanediol novel enantiomerically pure benzimidazoles were prepared; N-alkylation gave chiral benzimidazolium salts, which were tested in asymmetric benzoin condensations.
