Check Digit Verification of cas no

The CAS Registry Mumber 139588-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,8 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139588-97:
(8*1)+(7*3)+(6*9)+(5*5)+(4*8)+(3*8)+(2*9)+(1*7)=189
189 % 10 = 9
So 139588-97-9 is a valid CAS Registry Number.

Flexible strategy for differentially 3,5-disubstituted 4-oxypyridin-2(1H)- ones based on site-selective Pd-catalyzed cross-coupling reactions

Conreaux, David,Bossharth, Emmanuel,Monteiro, Nuno,Desbordes, Philippe,Vors, Jean-Pierre,Balme, Genevieve

, p. 271 - 274 (2007/10/03)

(Chemical Equation Presented) 3,5-Dihalogeno-4-methoxy-N-methylpyridin- 2(1H)-ones have been shown to undergo single Suzuki coupling reactions in a site-selective fashion. Monoarylations occur at the C-5 position preferentially, thus leaving the remaining
