(S)-3-BOC-AMINO-1-DIAZO-5-METHYLTHIO-2-PENTANONE is a chemical compound that belongs to the class of diazo compounds. It is a white crystalline powder that is used in organic synthesis as a reagent for the preparation of various organic compounds. The Boc-amino group in the molecule provides protection for the amino functionality during chemical reactions, while the diazo and methylthio groups contribute to its reactivity and selectivity in different types of reactions. (S)-3-BOC-AMINO-1-DIAZO-5-METHYLTHIO-2-PENTANONE is commonly used in the pharmaceutical industry for the synthesis of drug intermediates and active pharmaceutical ingredients. However, it is important to handle and use this compound with caution due to its potential hazards and risks associated with diazo compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 173472-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,4,7 and 2 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 173472-42:
(8*1)+(7*7)+(6*3)+(5*4)+(4*7)+(3*2)+(2*4)+(1*2)=139
139 % 10 = 9
So 173472-42-9 is a valid CAS Registry Number.
