Check Digit Verification of cas no

The CAS Registry Mumber 129409-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,0 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129409-76:
(8*1)+(7*2)+(6*9)+(5*4)+(4*0)+(3*9)+(2*7)+(1*6)=143
143 % 10 = 3
So 129409-76-3 is a valid CAS Registry Number.

Reactions of Methyl 10,11-epoxyundecanoate with Isothiocyanates: Synthesis of Fatty 1,3-Oxazolidine-2-thiones.

Ansari, Mohammad Hafeaz,Ahmad, Mashood

, p. 1733 - 1743 (2007/10/02)

The reaction of methyl 10,11-epoxyundecanoate (I) with p-fluoro-phenyl isothiocyanate in dimethylformamide (DMF) in the presence of lithium bromide (LiBr) as catalyst under refluxing conditions affords the respective N-p-fluorophenyl-1,3-oxazolidine-2-thione (I and 2-imino-1,3-oxathiolane (III) along with the unsubstituted 1,3-oxazolidine-2-thione (II) as a minor product.Similar treatment of I with allyl isothiocyanate also affords the respective N-allyl-1,3-oxazolidine-2-thione (VI) and 2-imino-1,3-oxathiolane (V) along with product II.The products have been characterized on the basis of spectral and microanalytical data.
