146983-31-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146983-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,9,8 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 146983-31:
(8*1)+(7*4)+(6*6)+(5*9)+(4*8)+(3*3)+(2*3)+(1*1)=165
165 % 10 = 5
So 146983-31-5 is a valid CAS Registry Number.

Diastereoselective synthesis of the top half of kijanolide
Roush,Brown
, p. 7309 - 7312 (2007/10/02)
A highly diastereoselective synthesis of the top half (4) of kijanolide is described. The key step is the exo and diastereoface selective Diels-Alder reaction of triene 6 and chiral dienophile 6.
