18178-54-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18178-54-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,7 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18178-54:
(7*1)+(6*8)+(5*1)+(4*7)+(3*8)+(2*5)+(1*4)=126
126 % 10 = 6
So 18178-54-6 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.
