Check Digit Verification of cas no

The CAS Registry Mumber 1299327-31-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,9,3,2 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1299327-31:
(9*1)+(8*2)+(7*9)+(6*9)+(5*3)+(4*2)+(3*7)+(2*3)+(1*1)=193
193 % 10 = 3
So 1299327-31-3 is a valid CAS Registry Number.

Efficient dichloromethylation of some aromatic hydrocarbons catalyzed by a new ionic liquid [C12minPEG800]br under homogeneous catalysis in aqueous media

Hu,Liu,Lu,Lu,Ge,Zhang

, p. 131 - 141 (2011)

A series of new imidazolium-type ionic liquids based on polyethylene glycol have been prepared. The new recyclable temperature-dependant phase-separation system comprised of [C12minPEG800]Br and methylcyclohexane was also developed and successfully applied to the dichloromethylation of some aromatic hydrocarbons to prepare dichloromethyl-substituted hydrocarbons in excellent yields. The ionic liquid could be excellent recycled without any apparent loss of catalytic activity and little loss of weight even after 8 times recycling.
