115217-04-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 115217-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,2,1 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 115217-04:
(8*1)+(7*1)+(6*5)+(5*2)+(4*1)+(3*7)+(2*0)+(1*4)=84
84 % 10 = 4
So 115217-04-4 is a valid CAS Registry Number.

, p. 588 - 592 (2007/10/02)
Indenestrol A (IA) is a metabolite of diethylstilbestrol (DES), and indenestrol B (IB) is an analog of IA. IA was simply obtained from E,E-dienestrol in the presence of dilute sulfuric acid, and a mixture of IA and IB was formed by thermal cyclization of
