Check Digit Verification of cas no
The CAS Registry Mumber 109508-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,0 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109508-79:
(8*1)+(7*0)+(6*9)+(5*5)+(4*0)+(3*8)+(2*7)+(1*9)=134
134 % 10 = 4
So 109508-79-4 is a valid CAS Registry Number.

Features of the reaction of unsymmetrical 2-mercapto-imidazoles with aromatic and aliphatic ketones
Dzhavakhishvili,Borisov,Nikitchenko,Kovalenko
, p. 98 - 105 (2007)
The cyclization of unsymmetrical 2-mercaptoimidazoles with aliphatic and aromatic ketones has been studied. Using 1H NMR and X-ray analysis it has been shown that 4-R1-1H-2-mercaptoimidazoles undergo selective oxidative cyclization t
