954416-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 954416-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,4,4,1 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 954416-33:
(8*9)+(7*5)+(6*4)+(5*4)+(4*1)+(3*6)+(2*3)+(1*3)=182
182 % 10 = 2
So 954416-33-2 is a valid CAS Registry Number.

Total synthesis of aspinolide B: a ring-closing metathesis approach
Ghosh, Subhash,Rao, R. Vengal
, p. 6937 - 6940 (2008/02/13)
A highly convergent stereoselective total synthesis of aspinolide B, a 10-membered lactone is described. The key step includes a ring-closing metathesis reaction to construct the 10-membered ring and the E-olefinic moiety. d-Mannitol was used as a chiral
