1187335-28-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1187335-28-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,3,3 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1187335-28:
(9*1)+(8*1)+(7*8)+(6*7)+(5*3)+(4*3)+(3*5)+(2*2)+(1*8)=169
169 % 10 = 9
So 1187335-28-9 is a valid CAS Registry Number.

Silylene transfer to α-keto esters and application to the synthesis of γ-lactones
Howard, Brett E.,Woerpel
experimental part, p. 6447 - 6453 (2011/02/26)
Disubstituted α-hydroxy acids have been synthesized by metal-catalyzed silylene transfer to α-keto esters. A range of substituents are tolerated in the transformation with the exception of branched groups at the vinylic position. The α-hydroxy acid produc
