129144-91-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129144-91-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,4 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129144-91:
(8*1)+(7*2)+(6*9)+(5*1)+(4*4)+(3*4)+(2*9)+(1*1)=128
128 % 10 = 8
So 129144-91-8 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.
