Check Digit Verification of cas no

The CAS Registry Mumber 873193-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,3,1,9 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 873193-16:
(8*8)+(7*7)+(6*3)+(5*1)+(4*9)+(3*3)+(2*1)+(1*6)=189
189 % 10 = 9
So 873193-16-9 is a valid CAS Registry Number.

, p. 3937 - 3947 (2007/10/03)

4-Hydroxy-5,5-dimethylimidazolines tethered at N-1 to an aryl sulfide undergo an unprecedented acid-catalysed domino reaction, involving double methyl transposition, heterocyclisation, isomerisation of thiazetidinium ion and, finally, π-cyclisation. In th
