566943-62-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 566943-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,6,9,4 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 566943-62:
(8*5)+(7*6)+(6*6)+(5*9)+(4*4)+(3*3)+(2*6)+(1*2)=202
202 % 10 = 2
So 566943-62-2 is a valid CAS Registry Number.

A new route to (+)-estrone using a bicyclo[3.2.1]octane chiral building block.
Hanada, Keisuke,Miyazawa, Norio,Ogasawara, Kunio
, p. 104 - 106 (2003)
A new route to (+)-estrone has been developed starting from the chiral building block having a bicyclo[3.2.1]octane framework based on the inherent stereochemical chemical nature of the chiral building block.
