Check Digit Verification of cas no

The CAS Registry Mumber 72765-11-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,7,6 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72765-11:
(7*7)+(6*2)+(5*7)+(4*6)+(3*5)+(2*1)+(1*1)=138
138 % 10 = 8
So 72765-11-8 is a valid CAS Registry Number.

Synthesis of 1,2,3,4-tetrachlorohexafluorobutane

Karimova,Glazkov,Ignatenko,Mysova

, p. 2336 - 2337 (2007/10/03)

The condensation of 1-iodo-1,2,2-trifluoro-1,2-dichloroethane induced by granulated Zn in the presence of catalytic amounts of AcOEt without a solvent results in 1,2,3,4-tetrachlorohexafluorobutane in high yield.

REACTION OF 2,2-DICHLOROTRIFLUORO-1-IODOETHANE WITH ZINC

Eapen, K. C.

, p. 17 - 28 (2007/10/02)

The zinc coupling reaction of a pure sample of 2,2-Dichlorotrifluoro-1-iodoethane (I) in acetic anhydride-methylene chloride has been investigated.The coupled product C4F6Cl4 was found to be a single isomer by 19F NMR and had the structure CFCl2CF2CF2CFCl2 (II).The probable modes of formation of by-products such as C6F9Cl5 and C8F12Cl6 are discussed.

Reaction of 1,2-Dichloroiodotrifluoroethane With Zinc

Eapen, K. C.,Tamborski, C.

, p. 421 - 424 (2007/10/02)

The zinc coupling reaction of 1,2-dichloroiodotrifluoroethane (I) in acetic anhydride-methylene chloride has been reinvestigated in more detail than its original disclosure.The expected coupling product C4F6Cl4 was shown to be an isomeric mixture of three components, CF2ClCFClCFClCF2Cl (II, 80percent), CFCl2CF2CF2CFCl2 (IIa, 15percent) and CF2ClCFClCF2CFCl2 (IIb, 5percent).In addition, other products e.g.CF2-CFCl, C6F9Cl5 and C8F12Cl6 were formed in minor quantities.A probable mode of formation of various byproducts via initial formation of CF2-CFCl and subsequent telomerization is presented.
