Check Digit Verification of cas no

The CAS Registry Mumber 1192139-91-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,1,3 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1192139-91:
(9*1)+(8*1)+(7*9)+(6*2)+(5*1)+(4*3)+(3*9)+(2*9)+(1*1)=155
155 % 10 = 5
So 1192139-91-5 is a valid CAS Registry Number.

Purification strategy for direct nucleophilic procedures

-

Page/Page column 22, (2009/12/02)

The present invention provides novel and advantageous processes for preparing and purifying chemical compounds such as pharmaceuticals. The processes comprise a nucleophilic substitution reaction with a moiety X wherein the leaving group L of a substrate S in the reaction is covalently attached to a purification moiety M. This concept offers a convenient and time-saving way to purify the desired product S-X from non-reacted precursors S-L-M and by-products L-M.
