Uses
(2R)-3-Chloro-2-[[4-(trifluoromethoxy)phenyl]methoxy]propyl ester 4-Methoxybenzoic Acid is an intermediate in the synthesis of novel anti-tuberculosis drug (S)-PA 824 (P122500).
Check Digit Verification of cas no
The CAS Registry Mumber 1253202-35-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,2,0 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1253202-35:
(9*1)+(8*2)+(7*5)+(6*3)+(5*2)+(4*0)+(3*2)+(2*3)+(1*5)=105
105 % 10 = 5
So 1253202-35-5 is a valid CAS Registry Number.
