Check Digit Verification of cas no

The CAS Registry Mumber 21295-88-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,9 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21295-88:
(7*2)+(6*1)+(5*2)+(4*9)+(3*5)+(2*8)+(1*8)=105
105 % 10 = 5
So 21295-88-5 is a valid CAS Registry Number.

Halogen-free room-temperature bronsted acidic ionic liquid [Hmim]+ HSO4- as a recyclable green "dual reagent" catalysis for the synthesis of triarylmethanes (TRAM s) ;

Mukhopadhyay, Chhanda,Datta, Arup,Tapaswi, Pradip Kumar

experimental part, p. 2453 - 2463 (2012/06/29)

The halogen-free Brnsted acidic ionic liquid methylimidazolium hydrogen sulfate ([Hmim]+ HSO4-) acts as a very efficient catalyst for the one-pot, two-component Baeyer condensation of a variety of aromatic aldehydes with dimethyl or diethyl aniline at room temperature. This green reagent behaves as both catalyst and solvent; that is, it exhibits dual-reagent catalysis. The room-temperature acidic ionic liquid could be recycled several times with almost no loss in the yield of the reaction. This is the first report of the Baeyer synthesis with a halogen-free ionic liquid.
