Check Digit Verification of cas no

The CAS Registry Mumber 1198278-74-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,2,7 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1198278-74:
(9*1)+(8*1)+(7*9)+(6*8)+(5*2)+(4*7)+(3*8)+(2*7)+(1*4)=208
208 % 10 = 8
So 1198278-74-8 is a valid CAS Registry Number.

Construction of 1,2,5-tricarbonyl compounds using methyl cyanoacetate as a glyoxylate anion synthon combined with copper(I) iodide-catalyzed aerobic oxidation

Kim, Se Hee,Kim, Ko Hoon,Kim, Jae Nyoung

, p. 3335 - 3339 (2012/01/19)

A practical and efficient synthesis of various 1,2,5-tricarbonyl compounds is described. The synthesis has been carried out by a conjugate addition of methyl cyanoacetate to the β-position of α,β-unsaturated carbonyl compounds and a subsequent copper(I) iodide-catalyzed aerobic oxidation. In addition, various α-aryl- and α-alkyl-α-keto esters have been synthesized using a similar approach. Copyright
