Check Digit Verification of cas no
The CAS Registry Mumber 859691-36-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,9,6,9 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 859691-36:
(8*8)+(7*5)+(6*9)+(5*6)+(4*9)+(3*1)+(2*3)+(1*6)=234
234 % 10 = 4
So 859691-36-4 is a valid CAS Registry Number.

Observations on the reactivity of pentafluorophenyl sulfonate esters
Caddick, Stephen,Wilden, Jonathan D.,Judd, Duncan B.
, p. 2727 - 2728 (2005)
Studies on displacement reactions of alkyl pentafluorophenyl (PFP) sulfonates with amines are consistent with a mechanism involving an elimination-addition pathway; comparisons between the reactivity of PFP-sulfonates with sulfonyl chlorides and PFP-sulfo
