Check Digit Verification of cas no
The CAS Registry Mumber 170836-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,8,3 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 170836-68:
(8*1)+(7*7)+(6*0)+(5*8)+(4*3)+(3*6)+(2*6)+(1*8)=147
147 % 10 = 7
So 170836-68-7 is a valid CAS Registry Number.

Method for the Synthesis of Cyclic Acetals by the Reactive Extraction of a Polyol in a Concentrated Solution
-
Page/Page column 5, (2010/05/13)
A method for the synthesis of cyclic acetals comprises reacting at least one carbonyl-function compound selected from aldehydes, ketones, and/or linear acetals, on a polyol in a concentrated aqueous solution exceeding 20 wt % in a reactor containing an acidic catalyst. The carbonyl-function compound is selected so that the cyclic acetal obtained has a water solubility lower than 20000 mg/kg. During the catalytic reaction for the cyclic acetal synthesis, at least one portion of the organic phase containing the cyclic acetal is separated. The acidic catalysis is either homogeneous when using a water-soluble strong acid, or heterogeneous when using a solid acid such as a resin, a zeolite, or any appropriately acidified solid. The extractive reaction method can be used for obtaining high conversions and selectivity.
