138879-13-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138879-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,7 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138879-13:
(8*1)+(7*3)+(6*8)+(5*8)+(4*7)+(3*9)+(2*1)+(1*3)=177
177 % 10 = 7
So 138879-13-7 is a valid CAS Registry Number.

Silyl Group-Transfer-Mediated Serial Michael Additions
Klimko, Peter G.,Singleton, Daniel A.
, p. 1733 - 1740 (2007/10/02)
Three protocols have been developed for achieving ordered, multiple (serial) Michael reactions initiated by silyl enol ethers or silyl ketene acetals.Anion (fluoride or m-chlorobenzoate) catalysis was most effective for reactions of silyl ketene acetal 2
