Check Digit Verification of cas no

The CAS Registry Mumber 68130-71-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,1,3 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68130-71:
(7*6)+(6*8)+(5*1)+(4*3)+(3*0)+(2*7)+(1*1)=122
122 % 10 = 2
So 68130-71-2 is a valid CAS Registry Number.

The method of manufacturing the ionic liquid

-

Paragraph 0111; 0115, (2016/12/26)

PROBLEM TO BE SOLVED: To provide an industrially simple method for producing an ionic liquid capable of giving combinations of various cations and anions.SOLUTION: The method for producing an ionic liquid includes a step of reacting an ammonium salt of a sulfuric ester (1), an ammonium salt of a phosphoric ester (2) or an ammonium salt of a sulfonic acid with a nitrogen-containing compound. In formula (1), Rindicates a 1C-20C substituted or unsubstituted, straight-chained, branched or cyclic alkyl group, a 6C-30C substituted or unsubstituted aryl group, or a 7C-31C substituted or unsubstituted arylalkyl group; Aindicates a 2C-4C substituted or unsubstituted, straight-chained or branched alkylene group; and n indicates an integer of 0-50. In formula (2), Rand Rindicate each independently a hydrogen atom, a 1-20C substituted or unsubstituted, straight-chained, branched or cyclic alkyl group, a 6-30C substituted or unsubstituted aryl group, or a 7-31C substituted or unsubstituted arylalkyl group, provided that Rand Rdo not simultaneously indicate a hydrogen atom; Aand Aindicate each independently a 2-4C substituted or unsubstituted, straight-chained or branched alkylene group; and m and q indicate each independently an integer of 0-50.
