Toluene-4-sulfonic acid (2R,3S)-3-((1S,3R,8S,9S,10R,13S,14S,17R)-1,3-bis-methoxymethoxy-10,13-dimethyl-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-17-yl)-2-hydroxy-butyl ester is a chemical with a specific purpose. Lookchem provides you with multiple data and supplier information of this chemical.
The CAS Registry Mumber 81897-53-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,9 and 7 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 81897-53: (7*8)+(6*1)+(5*8)+(4*9)+(3*7)+(2*5)+(1*3)=172 172 % 10 = 2 So 81897-53-2 is a valid CAS Registry Number.
