Check Digit Verification of cas no
The CAS Registry Mumber 789448-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,9,4,4 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 789448-80:
(8*7)+(7*8)+(6*9)+(5*4)+(4*4)+(3*8)+(2*8)+(1*0)=242
242 % 10 = 2
So 789448-80-2 is a valid CAS Registry Number.

Page/Page column 25, (2021/10/13)
The present application relates to methods of preparing 5R-[(benzyloxy) amino] piperidine-2S-carboxylic acid or its derivatives in an environment-friendly way. The method uses L-glutamic acid as a starting material, which is first subjected to esterification reaction in the presence of an acidic reagent, and then reacted successively with 2-haloacetate and N-protecting agent, or with N-protecting agent and 2-haloacetate under a basic condition to obtain compound IV; then, the obtained compound IV is subjected to intramolecular condensation into a ring under the action of a strong base to obtain N-protecting group piperidine-5-one-2S-carboxylate (V).
