4743-99-1 Usage

Preparation

To a refluxing solution of 5.0 gm (0.05 mole) of succinic anhydride in 100 ml of benzene is added a solution of 6.3 gm (0.05 mole) of O-ben- zylhydroxylamine in 20 ml of benzene. As soon as the addition has been completed, the reaction mixture is cooled, and the precipitated product is separated. Upon recrystallization from a benzene-methyl ethyl ketone mixture, 7.6 gm (68.2%) of N-benzyloxysuccinamic acid, m.p. 95-96°C isolated. A suspension of 4.3 gm (0.0193 mole) of this intermediate and a stron- tium carbonate catalyst containing 5% palladium in methyl ethyl ketone is hydrogenated. Upon working up the reaction mixture, 1.45 gm (56.7%) of succinomonohydroxamic acid, m.p. 95-96°C is isolated.

Check Digit Verification of cas no

The CAS Registry Mumber 4743-99-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,4 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4743-99:
(6*4)+(5*7)+(4*4)+(3*3)+(2*9)+(1*9)=111
111 % 10 = 1
So 4743-99-1 is a valid CAS Registry Number.
