Check Digit Verification of cas no
The CAS Registry Mumber 98190-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,1,9 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98190-85:
(7*9)+(6*8)+(5*1)+(4*9)+(3*0)+(2*8)+(1*5)=173
173 % 10 = 3
So 98190-85-3 is a valid CAS Registry Number.

Efficient procedures to prepare primary and secondary alkyl halides from alkanols via the corresponding sulfonates under mild conditions
Cahiez, Gerard,Gager, Olivier,Moyeux, Alban,Delacroix, Thomas
supporting information; experimental part, p. 1519 - 1528 (2012/07/03)
The study presented herein shows that sulfonate/halide exchange can be advantageously performed in THF to avoid several side reactions such as elimination and epimerization when the reaction is performed from a chiral alkyl sulfonate or a substrate having a C-H acidic chiral center. The main limitation of this procedure was found to be the conversion of secondary alkyl sulfonates to alkyl chlorides. In this case, the addition of a catalytic amount of manganese chloride clearly accelerates the rate and the efficiency of the reaction. Copyright
