118356-32-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118356-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,3,5 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 118356-32:
(8*1)+(7*1)+(6*8)+(5*3)+(4*5)+(3*6)+(2*3)+(1*2)=124
124 % 10 = 4
So 118356-32-4 is a valid CAS Registry Number.

Substituted Lithium (E)-3-Lithio-3-tosyl-2-propenolates: Useful Intermediates in Organic Synthesis
Najera, Carmen,Yus, Miguel
, p. 1491 - 1499 (2007/10/02)
The lithiation of substituted tosylated epoxides 7 derived from allylic sulfones with methyllithium leads to lithium (E)-3-lithio-3-tosyl-2-propenolates 5 in a stereoselective manner.The further reaction of these intermediates with different electrophilic
