Check Digit Verification of cas no

The CAS Registry Mumber 93855-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,8,5 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 93855-45:
(7*9)+(6*3)+(5*8)+(4*5)+(3*5)+(2*4)+(1*5)=169
169 % 10 = 9
So 93855-45-9 is a valid CAS Registry Number.

GOLD-CONTAINING PYRAZOLONES

Bonati, F.,Burini, A.,Pietroni, B.R.,Felici, M.

, p. 275 - 282 (1984)

Reaction of LAuCl with various pyrazol-5-ones and alkali in homogeneous or heterogeneous medium has given several 1-R-3-R'-4(LAu)2-pyrazol-5-one derivatives (R = H, phenyl, p-bromophenyl, tosyl, methyl; R' = methyl, trifluoromethyl; L = Ph3P or Et3P).In the case of 1-aryl-5-methylpyrazol-3-one 1-aryl-2-triphenylphosphinegold-5-methylpyrazol-3-one, a compound with an Au-N bond is formed.The scope, limitation, and characteristic of the auration reaction are discussed.
