144797-09-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144797-09-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,7,9 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144797-09:
(8*1)+(7*4)+(6*4)+(5*7)+(4*9)+(3*7)+(2*0)+(1*9)=161
161 % 10 = 1
So 144797-09-1 is a valid CAS Registry Number.

A stereoselective cis-enyne synthesis using vinyl sulfone chemistry
Holmes, Andrew B.,Pooley, Guy R.
, p. 7775 - 7792 (2007/10/02)
The trans-sulfonyl enyne 8 was deprotonated using lithium diisopropylamide to provide a cis-enyne onion which was coupled with a variety of carbonyl compounds to provide, in high yields, a range of silyl-protected phenylsulfonyl enynes. These were desulfo
