Check Digit Verification of cas no

The CAS Registry Mumber 129612-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,6,1 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129612-89:
(8*1)+(7*2)+(6*9)+(5*6)+(4*1)+(3*2)+(2*8)+(1*9)=141
141 % 10 = 1
So 129612-89-1 is a valid CAS Registry Number.

RADICAL TELOMERIZATION OF 3,3,3-TRIFLUORO-1-PROPENE WITH CARBON TETRACHLORIDE

Vasil'eva, T. T.,Fokina, I. A.,Vitt, S. V.,Dostovalova, V. I.

, p. 1638 - 1641 (2007/10/02)

Telomerization of 3,3,3-trifluoropropene with CCl4 was carried out in the presence of Fe(CO)5 in combination with dimethylformamide (DMF) or hexamethylphosphoric triamide (HMPA) with formation of the telomers CCl3(CH2CHCF3)nCl, n = 1-3, as the main products.Chromatography-mass spetrometry showed the presence of CCl3CH2CH(CCl3)CF3, a product of recombination of the adduct radical and CCl3, in the reaction mixture, which confirms the radical nature of the process.The structure of all the products was confirmed by 13C NMR and (or) mass spectrometry.
