1132970-09-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1132970-09-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,2,9,7 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1132970-09:
(9*1)+(8*1)+(7*3)+(6*2)+(5*9)+(4*7)+(3*0)+(2*0)+(1*9)=132
132 % 10 = 2
So 1132970-09-2 is a valid CAS Registry Number.

Total synthesis of bafilomycin A1
Kleinbeck, Florian,Carreira, Erick M.
supporting information; experimental part, p. 578 - 581 (2009/04/14)
A convergent synthesis of bafilomycin A1 (see structure) is presented, and relies on the Zn(OTf)2-mediated diastereoselective addition of alkynes to aldehydes. The coupling of a complex enyne with a sensitive aldehyde in the key step
