447450-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 447450-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,7,4,5 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 447450-19:
(8*4)+(7*4)+(6*7)+(5*4)+(4*5)+(3*0)+(2*1)+(1*9)=153
153 % 10 = 3
So 447450-19-3 is a valid CAS Registry Number.

Stereoselective total synthesis of epothilones by the metathesis approach involving C9-C10 bond formation
Sun, Jian,Sinha, Subhash C.
, p. 1381 - 1383 (2007/10/03)
A stereoselective synthesis of epothilone B was achieved by the metathesis of the diene 1, by use of a new Grubbs catalyst to form the C9-C10 bond, followed by hydrogenation and deprotection of 2; TBS = tert-butyldimethylsilyl.
