850621-29-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850621-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,6,2 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 850621-29:
(8*8)+(7*5)+(6*0)+(5*6)+(4*2)+(3*1)+(2*2)+(1*9)=153
153 % 10 = 3
So 850621-29-3 is a valid CAS Registry Number.

Synthesis of epothilones via a silicon-tethered RCM reaction
Gaich, Tanja,Mulzer, Johann
, p. 1311 - 1313 (2005)
(Chemical Equation Presented) A short synthesis of epothilone B and D is reported. The key step for generating the C12-13-trisubstituted Z-double bond uses a ring-closing metathesis reaction of a disiloxane to form a nine-membered silicon-tethered ring.
