2539-13-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2539-13-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,3 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2539-13:
(6*2)+(5*5)+(4*3)+(3*9)+(2*1)+(1*3)=81
81 % 10 = 1
So 2539-13-1 is a valid CAS Registry Number.

Jain, Subhash C.,Kumar, Ravindra,Gupta, Bhavna,Olsen, Carl E.
, p. 2200 - 2202 (2007/10/03)
Phytochemical investigation of the fungus, F. fastuosus has led to the isolation of a new triterpene, lanosta-8,17,25-trien-3β-ol 1 and two isomeric trichlorotrimethoxybenzenes, viz., 1,2,3-trichloro-4,5,6-trimethoxybenzene 2 and 1,2,4-trichloro-3,5,6-tri
