Check Digit Verification of cas no

The CAS Registry Mumber 233279-11-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,3,2,7 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 233279-11:
(8*2)+(7*3)+(6*3)+(5*2)+(4*7)+(3*9)+(2*1)+(1*1)=123
123 % 10 = 3
So 233279-11-3 is a valid CAS Registry Number.

α-dicarbonylmonoximes as nucleophiles and neighbour groups

M?hrle, Hans,Keller, Georg

, p. 632 - 642 (2007/10/03)

The α-dicarbonylmonooximes 1 and 11 do not react as simple "CH-acidic-compounds" in the Mannich condensation. In a concerted reaction with aminals in absolute dioxane they give rise to the products 4a - e and 12a - e with better practicability and much higher yields compared with the conventional method. The Mannich bases with a cyclic amine part show in the dehydrogenation, using mercury-EDTA, a neighbouring group participation of the oxime in type 4 and of the oxime or amide function in 12 yielding cyclized products. For the reaction a plausible mechanism is proposed.
