Check Digit Verification of cas no
The CAS Registry Mumber 23357-47-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,3,5 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 23357-47:
(7*2)+(6*3)+(5*3)+(4*5)+(3*7)+(2*4)+(1*7)=103
103 % 10 = 3
So 23357-47-3 is a valid CAS Registry Number.

Paragraph 0006; 0015; 0017, (2018/03/13)
The invention relates to a preparation method of a palonosetron hydrochloride key intermediate (S)-1,2,3,4-tetrahydro-1-naphthoic acid as shown in a formula (I). The method comprises the following steps of adding a resolution agent for resolution by adopting 1,2,3,4-tetrahydro-naphthalene acid racemate as a raw material to obtain a salt (III) formed by a (S)-1,2,3,4-tetrahydro naphthalene acid and the resolution agent, and a salt (IV) formed by (R)-1,2,3,4-tetrahydro naphthalene acid and the resolution agent; carrying out salt removing on a compound III and a compound IV separately to obtain compounds (I) and (II); and carrying out racemization on the compound (II) under an alkaline condition to obtain a starting material 1,2,3,4-tetrahydro-naphthalene acid racemate and further carrying out resolution according to the steps. Therefore, the overall yield can be greatly improved, the production cost is reduced and environmental protection is facilitated. The preparation technology of the palonosetron hydrochloride key intermediate provided by the invention is different from the prior art, is safe, environmentally friendly, simple in operation and high in yield, and has relatively great practical value. The formula is as shown in the specification.
