Check Digit Verification of cas no
The CAS Registry Mumber 33964-04-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,6 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33964-04:
(7*3)+(6*3)+(5*9)+(4*6)+(3*4)+(2*0)+(1*4)=124
124 % 10 = 4
So 33964-04-4 is a valid CAS Registry Number.

Yttrium Nitrate mediated Nitration of Phenols at room temperature in Glacial Acetic acid
Mondal, Mohabul A,Mandal, Debashis,Mitra, Kanchan
, p. 39 - 43 (2017/01/24)
Rapid nitration of electron rich phenols using Y(NO 3) 3.6H 2O in glacial acetic acid at room temperature was observed with good yield. The method allows nitration of phenols without oxidation, and isolation of nitration product in a rapid and simple way. The described method is selective for phenols.
