Check Digit Verification of cas no

The CAS Registry Mumber 1034596-22-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,4,5,9 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1034596-22:
(9*1)+(8*0)+(7*3)+(6*4)+(5*5)+(4*9)+(3*6)+(2*2)+(1*2)=139
139 % 10 = 9
So 1034596-22-9 is a valid CAS Registry Number.

Indium-mediated 1,2,4,5-hexatetraen-3-ylation of 4-acetoxy-2-azetidinones and their applications to the Diels-Alder reactions for the synthesis of 2-azetidinone derivatives

Yu, Heashim,Lee, Phil Ho

, p. 5183 - 5186 (2008/12/20)

(Chemical Equation Presented) 4-Acetoxy-2-azetidinones reacted with organoindium reagent generated in situ from indium and 1,6-dibromo-2,4-hexadiyne in the presence of LiCl in DMF to selectively produce 2-azetidinones possessing 1,2,4,5-hexatetraen-3-yl group on the C4-position. The Diels-Alder reactions of 4-(1,2,4,5-hexatetraen-3-yl)-2-azetidinones with a variety of dienophiles and subsequent aromatizations afforded valuable functional group-substituted 2-azetidinones in good yields.
