98342-59-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98342-59-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,3,4 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98342-59:
(7*9)+(6*8)+(5*3)+(4*4)+(3*2)+(2*5)+(1*9)=167
167 % 10 = 7
So 98342-59-7 is a valid CAS Registry Number.

A FACILE AND CONVENIENT SYNTHESIS OF LIPOPHILIC TETRAALKYLAMMONIUM OR PHOSPHONIUM HYDROGEN SULFATES
Giorgi, Marco De,Landini, Dario,Maia, Angelamaria,Penso, Michele
, p. 521 - 534 (2007/10/02)
Lipophilic tetraalkylammonium or phosphonium hydrogen sulfates are easily synthesized in very high yields by action of KHSO4 in 10percent aqueous sulfuric acid on the corresponding quaternary azides, the latter being obtained by preparative ion-pair extraction from quaternary methanesulfonates or chlorides.
