Check Digit Verification of cas no

The CAS Registry Mumber 41280-37-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,2,8 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 41280-37:
(7*4)+(6*1)+(5*2)+(4*8)+(3*0)+(2*3)+(1*7)=89
89 % 10 = 9
So 41280-37-9 is a valid CAS Registry Number.

A mild, nonbasic synthesis of thioethers. The copper-catalyzed coupling of boronic acids with N-thio(alkyl, aryl, heteroaryl)imides

Savarin, Cecile,Srogl, Jiri,Liebeskind, Lanny S.

, p. 4309 - 4312 (2002)

(equation presented) A new synthesis of thioethers is described. The reaction of boronic acids with aryl, heteroaryl, and alkyl N-thioimides in the presence of catalytic quantities of a Cu(I) carboxylate affords good to excellent yields of thioethers. This reaction takes place in the absence of a base under mild conditions (THF, 45-50°C, 2.5-12 h) and represents an interesting complement to known methods for thioether synthesis.
