Check Digit Verification of cas no

The CAS Registry Mumber 169693-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,6,9 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 169693-89:
(8*1)+(7*6)+(6*9)+(5*6)+(4*9)+(3*3)+(2*8)+(1*9)=204
204 % 10 = 4
So 169693-89-4 is a valid CAS Registry Number.

Synthesis of 3-Acyl- and 3-Carbamoylflavones

Ellemose, Steen,Kure, Niels,Torsell, Kurt B. G.

, p. 524 - 529 (2007/10/02)

Routes to 3-acyl-, 3-carboxamido- and polyhydroxylated flavones have been devised by application of isoxazole methodology and Heck-Stille couplings.Reductive ring opening of 3-alkoxyisoxazoles gives β-keto carboxamides in contrast with 3-alkoxy-2-isoxazolines, which give β-hydroxy esters.
