(1S,4aS,10bS)-4,4-Dimethyl-2-oxo-1,4a,5,10b-tetrahydro-2H,4H-pyrano[3,4-c]chromene-1-carboxylic acid ((1S,2R)-2-hydroxy-1-methyl-2-phenyl-ethyl)-methyl-amide is a chemical with a specific purpose. Lookchem provides you with multiple data and supplier information of this chemical.
The CAS Registry Mumber 98720-26-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,2 and 0 respectively; the second part has 2 digits, 2 and 6 respectively. Calculate Digit Verification of CAS Registry Number 98720-26: (7*9)+(6*8)+(5*7)+(4*2)+(3*0)+(2*2)+(1*6)=164 164 % 10 = 4 So 98720-26-4 is a valid CAS Registry Number.
