Check Digit Verification of cas no

The CAS Registry Mumber 1023971-91-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,9,7 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1023971-91:
(9*1)+(8*0)+(7*2)+(6*3)+(5*9)+(4*7)+(3*1)+(2*9)+(1*1)=136
136 % 10 = 6
So 1023971-91-6 is a valid CAS Registry Number.

Recent advances in electrophilic CF3-transfer using hypervalent iodine(III) reagents

Kieltsch, Iris,Eisenberger, Patrick,Stanek, Kyrill,Togni, Antonio

, p. 260 - 263 (2008)

The development of new methodologies for an efficient introduction of CF3 groups into complex molecules constitutes one of the most challenging tasks of modern organic chemistry. Recently, we reported the access to a new class of electrophilic CF3-transfer reagents based on hypervalent iodine. The versatile application of these reagents to C-centred nucleophiles, such as β-keto esters, silyl enol ethers and α-nitro esters, as well as to thiols and primary and secondary phosphines is described. Experiments with phenols afforded corresponding trifluomethylethers in very low yields. Schweizerische Chemische Gesellschaft.
