132553-87-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 132553-87-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,5,5 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132553-87:
(8*1)+(7*3)+(6*2)+(5*5)+(4*5)+(3*3)+(2*8)+(1*7)=118
118 % 10 = 8
So 132553-87-8 is a valid CAS Registry Number.

An efficient synthesis of N-alkyl-4-substituted 3H-pyridine-2,6-dione. Synthesis of isoguvacine and MDL-11,939

Chang, Meng-Yang,Chen, Shui-Tein,Chang, Nein-Chen

, p. 2321 - 2334 (2007/10/03)

An efficient route towards the synthesis of N-alkyl-4-substituted 3H-pyridine-2,6-dione using various N-alkyl-α-sulfonylacetamides and two α,β-unsaturated esters as starting materials is described. Isoguvacine and MDL-11,939 with have potential biological activities were synthesized via this strategy.
