(3R,6S,1'RS)-3-(2-Chloro-1-hydroxy-1-phenylethyl)-3,6-dihydro-6-isopropyl-2,5-dimethoxypyrazine is a complex organic compound with a unique molecular structure. It is characterized by a pyrazine core, which is a six-membered heterocyclic ring containing two nitrogen atoms. The compound features a 2-chloro-1-hydroxy-1-phenylethyl group attached to the 3-position of the pyrazine ring, and an isopropyl group at the 6-position. Additionally, it has two methoxy groups at the 2 and 5 positions of the pyrazine ring. The stereochemistry of the compound is defined by the R configuration at the 3 and 6 positions, and the RS configuration at the 1' position, indicating a mixture of R and S enantiomers at this site. This chemical is likely to be found in specialized applications, such as pharmaceuticals or agrochemicals, due to its intricate structure and potential biological activity.

Check Digit Verification of cas no

The CAS Registry Mumber 98759-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,5 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 98759-50:
(7*9)+(6*8)+(5*7)+(4*5)+(3*9)+(2*5)+(1*0)=203
203 % 10 = 3
So 98759-50-3 is a valid CAS Registry Number.
