Check Digit Verification of cas no

The CAS Registry Mumber 124737-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,7,3 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 124737-13:
(8*1)+(7*2)+(6*4)+(5*7)+(4*3)+(3*7)+(2*1)+(1*3)=119
119 % 10 = 9
So 124737-13-9 is a valid CAS Registry Number.

FLUORID-KATALYSIERTE MICHAEL-ADDITION VON 2,2,2-TRIFLUORNITROALKANEN AN AKTIVIERTE MONOOLEFINE

Baasner, B.,Marhold, A.,Negele, M

, p. 161 - 172 (2007/10/02)

The fluoride catalyzed addition of 2,2,2-trifluoronitroalkanes CF3CH2NO2 (Ia) and CF3CH(CH3)NO2 (Ib) to activated carbon-carbon double bonds was applied to the synthesis of functionalized trifluoromethyl nitroalkanes CF3C(R)NO2C(R1R2)CH(R3)Y (II) (R=H, CH3).The influence of steric and electronic factors on the formation of the adducts (II) was investigated via systematic variation of the activating group Y, and the substituents (R1, R2, R3) on the double bond. --- The trifluoromethyl nitroalkanes reported represent a class of compounds which are possible intermediates for the synthesis of biologically active compounds.
