188568-01-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188568-01-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,5,6 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 188568-01:
(8*1)+(7*8)+(6*8)+(5*5)+(4*6)+(3*8)+(2*0)+(1*1)=186
186 % 10 = 6
So 188568-01-6 is a valid CAS Registry Number.

A stereoselective total synthesis of (-)-rishitin
Chen, Jiong,Marx, John N.
, p. 1889 - 1892 (2007/10/03)
A new synthesis of (-)-rishitin (1) is reported, starting with chiral pool molecules. The crucial step is a stereoselective vinyl radical cyclization, which gives a 10:1 ratio of 21 to 22.
