1344713-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1344713-80-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,4,7,1 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1344713-80:
(9*1)+(8*3)+(7*4)+(6*4)+(5*7)+(4*1)+(3*3)+(2*8)+(1*0)=149
149 % 10 = 9
So 1344713-80-9 is a valid CAS Registry Number.

Gold(I)-catalyzed synthesis of benzoxocines by an 8-endo-dig cyclization
Wittstein, Kathrin,Kumar, Kamal,Waldmann, Herbert
, p. 9076 - 9080 (2011/10/12)
A golden dig! Gold-catalyzed direct access to functionalized 2H-1-benzoxocines, eight-membered-ring ethers, is described. This unprecedented synthesis of benzoxocines occurs by an 8-endo-dig cyclization of the 1,7-enyne substrates. Copyright
