679841-60-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 679841-60-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,9,8,4 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 679841-60:
(8*6)+(7*7)+(6*9)+(5*8)+(4*4)+(3*1)+(2*6)+(1*0)=222
222 % 10 = 2
So 679841-60-2 is a valid CAS Registry Number.

An approach to open-chain 1,5-stereocontrol using a silyl group
Fleming,Ramarao
, p. 2185 - 2186 (2007/10/03)
Nucleophilic attack by an ethylcuprate on the α,β-unsaturated ketone 3 takes place anti to the silyl group to give largely (96:4) a single product 4, fragmentation of which removes the silyl group, and reveals a pair of stereogenic centres having an open-chain 1,5 relationship 9.
