Check Digit Verification of cas no

The CAS Registry Mumber 134939-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,3 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134939-08:
(8*1)+(7*3)+(6*4)+(5*9)+(4*3)+(3*9)+(2*0)+(1*8)=145
145 % 10 = 5
So 134939-08-5 is a valid CAS Registry Number.

Functionalized Oxovanadium Alkoxides - Potential Haptens

Hillerns, Frank,Rehder, Dieter

, p. 2249 - 2254 (2007/10/02)

Several new oxovanadium alkoxides and alkoxides/chlorides of the composition VOCl3-n(OR)n (n = CPh3; n = 2 and 3, R = CPh3, iBu, cyclopentyl, tert-pentyl, octyl; n 3, R = dodecyl, 3-methylbutyl) and the mixed ester VO(OiBu)-(OCPh3)2 have been prepared.The compounds VO(OiBu)2OR' have ben synthesized, where R' is a functionalized long-chain alkyl group .The chloride/carboxylate VOCl2 has also been obtained.The compounds are characterized, inter alia, by 51V-NMR spectroscopy.Typical 51V shift ranges are observed for specific ligand functionalities (chlorides, alkoxide, carboxylate). δ(51V) values also depend on the steric requirement of the groups R and the coordination number.The importance of the functionalized esters as potential triggers for the production of abzymes with phosphatase activity is discussed.Key Words: Vanadium Alkoxides / Haptens / NMR, 51V
