Check Digit Verification of cas no

The CAS Registry Mumber 143914-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,9,1 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143914-91:
(8*1)+(7*4)+(6*3)+(5*9)+(4*1)+(3*4)+(2*9)+(1*1)=134
134 % 10 = 4
So 143914-91-4 is a valid CAS Registry Number.

Stereoselective silver triflate-mediated iodocyclization of carbamates

Guindon,Slassi,Ghiro,Bantle,Jung

, p. 4257 - 4260 (2007/10/02)

Iodocyclization of carbamates involving electron-deficient olefins, (i.e. α,β-unsaturated esters) is greatly facilitated by the use of silver(l) triflate and proceeds with excellent trans ring stereoselectivity. During this process, the resultant iodides can undergo epimerization, the rate of which is solvent-dependent.
