Check Digit Verification of cas no

The CAS Registry Mumber 125229-61-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,2,2 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 125229-61:
(8*1)+(7*2)+(6*5)+(5*2)+(4*2)+(3*9)+(2*6)+(1*1)=110
110 % 10 = 0
So 125229-61-0 is a valid CAS Registry Number.

Preparation method of stable isotope labeled alprazolam and estazolam internal standard reagent

-

, (2021/10/27)

The invention relates to a preparation method of a stable isotope labeled alprazolam and estazolam internal standard reagent for monitoring the blood concentration of a clinical treatment drug, and belongs to a standard substance for monitoring the clinical treatment drug. The stable isotope labeled alprazolam or stable isotope labeled estazolam is obtained by taking stable isotope labeled phenylboronic acid as a raw material, performing catalytic addition, acylation, cyclization, sulfur-oxygen exchange and cyclization and finally conducting separating and purifying. The process has the advantages that raw materials needed for synthesis are simple and easy to obtain, reaction conditions are mild, the chemical purity of the target product stable isotope labeled alprazolam and stable isotope labeled estazolam can reach 98% or above, and the isotope abundance can reach 98% or above. The preparation method can meet the technical requirements of a stable isotope labeling internal standard reagent required by a liquid chromatography-tandem mass spectrometry method for monitoring the blood concentration of a clinical treatment drug.
