91171-17-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91171-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,7 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91171-17:
(7*9)+(6*1)+(5*1)+(4*7)+(3*1)+(2*1)+(1*7)=114
114 % 10 = 4
So 91171-17-4 is a valid CAS Registry Number.

A Facile Synthesis of Ketene O,N-Acetals and Ketene O,O-Acetals by Tosylate Elimination

Reuther, Wolfgang,Ruland, Alfred,Baus, Ulf

, p. 235 - 240 (2007/10/02)

Reaction of the alcohols 4 and 5 with p-toluensulfonyl chloride leads to the sulfonic esters 6 and 7, respectively, which on treatment with potassium tert-butylate easily react to give the ketene O,N-acetals 8 and O,O-acetals 9, respectively.The (E/Z) isomers 8 arising from the elimination reaction of 7 were identified by their 1H-NMR data after X-ray analysis of one of the isomers of 8e.On one example it is shown that the elimination reaction proceeds stereoselectively "anti".
