Check Digit Verification of cas no

The CAS Registry Mumber 1002965-83-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,2,9,6 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1002965-83:
(9*1)+(8*0)+(7*0)+(6*2)+(5*9)+(4*6)+(3*5)+(2*8)+(1*3)=124
124 % 10 = 4
So 1002965-83-4 is a valid CAS Registry Number.

Regioselective copper-catalyzed C-N and C-S bond formation using amines, thiols and halobenzoic acids

Liu, Shuanglong,Pestano, John Paul C.,Wolf, Christian

, p. 3519 - 3527 (2008/09/19)

A regioselective method for highly efficient C-N and C-S bond formation with 2-halobenzoic acids is described. The Cu/Cu2O-catalyzed reaction is carried out in 2-ethoxyethanol or ethylene glycol diethyl ether and does not require the use of strong base or other additives. This procedure eliminates the need for acid protection, tolerates a wide range of functional groups and provides aromatic and aliphatic amines and sulfides in 81-99% yield.
