The CAS Registry Mumber 81668-02-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,6 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81668-02:
(7*8)+(6*1)+(5*6)+(4*6)+(3*8)+(2*0)+(1*2)=142
142 % 10 = 2
So 81668-02-2 is a valid CAS Registry Number.

FREE RADICAL SUBSTITUTION. PART 34. THE CHLORINATION OF 1- AND 2-NITROBUTANES IN THE GAS AND LIQUID PHASES

Saeed-y-Atto,Potter, Alan,Singh, Hari,Tedder, John M.

, p. 139 - 142 (2007/10/02)

1- and 2-nitrobutanes have been chlorinated in the gas phase and in solution.The intermediate nitrobutyl radicals with the nitro-group in a β-position are unstable and in the gas phase lose NO2 to yield the corresponding butene.The relative rates of attack at the various sites have been determined.The nitro-group proves to be the most deactivating non-ionic substituent studied so far.
