Check Digit Verification of cas no

The CAS Registry Mumber 140837-96-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,3 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 140837-96:
(8*1)+(7*4)+(6*0)+(5*8)+(4*3)+(3*7)+(2*9)+(1*6)=133
133 % 10 = 3
So 140837-96-3 is a valid CAS Registry Number.

Further Reactions of t-Butyl 3-Oxobutanthioate and t-Butyl 4-Diethylphosphono-3-oxobutanthioate: Carbonyl Coupling Reactions, Amination, Use in The Preparation of 3-Acyltetramic Acids and Application to The Total Synthesis of Fuligorubin A.

Key words: Acyltetramic acid; Phosphonate; Wadsworth-Emmons; Dieckmann cyclisation; Fuligorubin A. Abstract: The use of t-butyl-3-oxobutanthioate (1) and t-butyl 4-diethylphosphono-3-oxobuthanthioate (2) for the preparation of homologated derivatives suitable for amination in the presence of silver(I) trifluoroacetate to afford the corresponding β-ketoamides is discussed.In particular Wadsworth-Emmons coupling reactions of (2) with various carbonyl compounds gave good yields of E-substituted products.Many of the β-ketoamides were shown to be suitable precursors for 3-acyltetramic acids using a Dieckman cyclisation with tetra-n-butyl ammonium fluoride as the cyclising base.These new reactions were applied to the total synthesis of the polyene 3-acyltetramic acid fuligorubin A.
