Check Digit Verification of cas no

The CAS Registry Mumber 1309932-49-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,9,3 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1309932-49:
(9*1)+(8*3)+(7*0)+(6*9)+(5*9)+(4*3)+(3*2)+(2*4)+(1*9)=167
167 % 10 = 7
So 1309932-49-7 is a valid CAS Registry Number.

Synthesis of oxazolidinone and tosyl enamines by tertiary amine catalysis

Eddy, Nicholas A.,Morse, Peter D.,Morton, Martha D.,Fenteany, Gabriel

supporting information; experimental part, p. 699 - 701 (2011/05/04)

A procedure for the synthesis of oxazolidinone and tosyl enamines is reported. Alkynoyl oxazolidinones and tosyl imides undergo reaction to form enamines in the presence of catalytic amounts of tertiary amines. The data suggest that an amide anion is formed during the reaction, which undergoes conjugate addition to form the final product. Georg Thieme Verlag Stuttgart - New York.
