31400-19-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31400-19-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,0 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 31400-19:
(7*3)+(6*1)+(5*4)+(4*0)+(3*0)+(2*1)+(1*9)=58
58 % 10 = 8
So 31400-19-8 is a valid CAS Registry Number.

An expeditious and solvent free synthesis of azine derivatives using sulfated anatase-titania as a novel solid acid catalyst
Krishnakumar,Swaminathan
, p. 50 - 55 (2011)
Solid acid catalyst sulfated anatase-titania (TiO2-SO 42-) has been used for the synthesis of azine derivatives from benzophenone hydrazone and ketones/aldehydes by simple physical grinding. This sulfated titania gives an
