Check Digit Verification of cas no

The CAS Registry Mumber 219583-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,5,8 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 219583-77:
(8*2)+(7*1)+(6*9)+(5*5)+(4*8)+(3*3)+(2*7)+(1*7)=164
164 % 10 = 4
So 219583-77-4 is a valid CAS Registry Number.

Palladium(0)-catalyzed allylation of highly acidic and non-nucleophilic arenesulfonamides, sulfamide, and cyanamide. I.

Cerezo, Silvia,Cortes, Jordi,Moreno-Manas, Marcial,Pleixats, Roser,Roglans, Anna

, p. 14869 - 14884 (2007/10/03)

Arenesulfonamides, sulfamide, and cyanamide are efficiently allylated using allylic carbonates under Pd(0)-catalysis. N-Arenesulfonyl-2,5- dihydropyrroles are obtained by ruthenium-mediated ring closing metathesis of the corresponding N-diallylated compounds. A stereochemical study of the reactions of ethyl cis-(5-methyl-2-cyclohexenyl) carbonate with 2,4,6- triisopropylphenylsulfonamide was performed, clean overall retention of configuration being found with bidentate phosphines.
