Check Digit Verification of cas no

The CAS Registry Mumber 131497-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,4,9 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131497-57:
(8*1)+(7*3)+(6*1)+(5*4)+(4*9)+(3*7)+(2*5)+(1*7)=129
129 % 10 = 9
So 131497-57-9 is a valid CAS Registry Number.

The retro-Diels-Alder-reactivity of 1,4,3,-oxathiazin-4-oxides

Pfeifer,Himbert

, p. 5725 - 5728 (1990)

1,4,3-oxathiazin-4-oxides 3 and 8, formed by (4+2) cycloaddition of ynamines 1a-d or phenylacetylene 7 with N-sulfinyl-p-toluamide 2, furnish p-tolunitrile 5 and the acyl-sulfines 4 and 9 by a retro-Diels-Alder reaction.

α-ACYL-SULFINES BY REACTION OF ACETYLENES WITH N-SULFINYL-AMIDES

Himbert, Gerhard,Pfeifer, Klaus-Peter,Finkele, Christoph E.

, p. 125 - 128 (2007/10/02)

Ynamines, ynethers and phenylacetylene react with N-sulfinyl-carboxamides to give 1,4,3-oxathiazines, which tend to devide by a retro Diels-Alder reaction into nitriles and 2-sulfinyl-amides, 2-sulfinyl-esters and sulfinylacetophenone, resp.
