528870-28-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 528870-28-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,8,8,7 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 528870-28:
(8*5)+(7*2)+(6*8)+(5*8)+(4*7)+(3*0)+(2*2)+(1*8)=182
182 % 10 = 2
So 528870-28-2 is a valid CAS Registry Number.

The Stereochemistry of Epoxidation of Δ5-Steroids with Sodium Perborate and Potassium Permanganate
Hanson, James R.,Terry, Nicolas,Uyanik, Cavit
, p. 50 - 51 (1998)
Sodium perborate, with potassium permanganate as a catalyst, has been shown to be a novel reagent for the epoxidation of steroidal 5-enes with the attack occurring predominantly on the β-face.
