Check Digit Verification of cas no

The CAS Registry Mumber 34690-94-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,6,9 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 34690-94:
(7*3)+(6*4)+(5*6)+(4*9)+(3*0)+(2*9)+(1*4)=133
133 % 10 = 3
So 34690-94-3 is a valid CAS Registry Number.

Copper-catalyzed formation of sulfur-nitrogen bonds by dehydrocoupling of thiols with amines

Taniguchi, Nobukazu

experimental part, p. 2670 - 2673 (2010/07/18)

Copper-catalyzed formation of sulfur-nitrogen bonds can be performed by a dehydrocoupling of aryl thiols with amines. Sulfenamides or sulfonamides can be produced by the use of a copper catalyst in air or under oxygen atmosphere. Furthermore, a reaction involving the combination of a palladium catalyst and a copper catalyst selectively afforded sulfinamides.
