Check Digit Verification of cas no

The CAS Registry Mumber 4459-83-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,5 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4459-83:
(6*4)+(5*4)+(4*5)+(3*9)+(2*8)+(1*3)=110
110 % 10 = 0
So 4459-83-0 is a valid CAS Registry Number.

Process for producing aromatic compound derivative by reaction of aromatic compound substituted with sulfamoyloxy, sulfinamoyloxy, or carbamoyloxy group, with nucleophilic agent

-

Page/Page column 26; 27, (2008/06/13)

A process for producing a compound represented by the following formula (I), which includes causing a compound represented by formula (II) to react with a nucleophilic agent: wherein X represents a substituent; R1 represents an electron-withdrawing substituent having a Hammett σp constant of more than 0; m represents an integer of 1 to 5; R2 represents a substituent; n represents an integer of 0 to 4; and m + n is from 1 to 5; wherein R1, m, R2, and n each have the same meanings to those in formula (I); R3 and R4 each independently represent an alkyl, aryl, or heterocyclic group; and Z represents C=O or S(O)p, wherein p is 1 or 2.
