Check Digit Verification of cas no

The CAS Registry Mumber 1217899-39-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,8,9 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1217899-39:
(9*1)+(8*2)+(7*1)+(6*7)+(5*8)+(4*9)+(3*9)+(2*3)+(1*9)=192
192 % 10 = 2
So 1217899-39-2 is a valid CAS Registry Number.

Copper-mediated n-heteroarylation of primary sulfonamides: Synthesis of mono-n-heteroaryl sulfonamides

Baffoe, Jonathan,Hoe, Madelene Y.,Barry Tou Re

supporting information; experimental part, p. 1532 - 1535 (2010/06/19)

"Figure Presented" We describe the coupling of primary sulfonamides and various halogenated heterocyclic cores, with an emphasis on 2-heteroaryl halides, via copper catalysis. These studies enabled the synthesis of many new mono-N-heteroaryl sulfonamides.
