The CAS Registry Mumber 127309-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,3,0 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 127309-06:
(8*1)+(7*2)+(6*7)+(5*3)+(4*0)+(3*9)+(2*0)+(1*6)=112
112 % 10 = 2
So 127309-06-2 is a valid CAS Registry Number.

Nitrosonium Ion Promoted Iodination and 1,2-Iodofunctionalization of Cyclohexene

Radner, Finn

, p. 902 - 907 (2007/10/02)

The promoting influence of NO+BF4- on the addition of I2 or 'I+Nu-' couples to cyclohexene (1) in the presence of O2 is described. 1-Acetoxy-2-iodocyclohexane is obtained in 89percent isolated yield from the reaction of I2, 1 and CH3COOH in CH2Cl2, and the corresponding methoxy- and acetamido-substituted iodocyclohexanes are obtained in 96 and 92percent yield, when methanol and acetonitrile, respectively, are added.Applications of the method to the synthesis of cis-1,2-cyclohexanediol (Woodward reaction) and bis(2-iodocyclohexyl) ether is described.
