78226-05-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78226-05-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,2,2 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78226-05:
(7*7)+(6*8)+(5*2)+(4*2)+(3*6)+(2*0)+(1*5)=138
138 % 10 = 8
So 78226-05-8 is a valid CAS Registry Number.

UEBER EINE trans-EINFLUSS-REIHE DER ORGANYLANIONEN AUS 13C-NMR-SPEKTROSKOPISCHEN UNTERSUCHUNGEN VON ORGANYLQUECKSILBERISOBUTYLVERBINDUNGEN

Steinborn, Dirk,Taube, Rudolf,Radeglia, Reiner,Hoebold, Wolfram

, p. 139 - 148 (1981)

The 1J(199Hg-13C) coupling constants of isobutylmercury compounds RHgCH2CHMe2 (R=organo group) have been measured and compared to the coupling constants of diisobutylmercury and diorganomercury compounds HgR2.Between the coupling constants 1J(Hg-Ci-Bu) and 1J(Hg-CR), which have been normalized to the coupling constants of the symmetric compounds concerned, a linear relation has been found.This relation, which can be deduced from the Fermi contact term on the basis of the simple hybrid orbital model, shows that the coupling constant 1J(Hg-Ci-Bu) reflects the s-character of the mercury hybrid orbital concerned and accordingly the NMR trans-influence of the organo group R.The NMR trans-influence decreases in the sequence t-Bu > i-Pr ca. cyclo-C6H11 > Et ca. n-Pr ca. n-Bu ca. i-Bu > CH2Ph ca.CH2CH=CH2 ca.Me > CH2SiMe3 > Ph ca.CH=CH2 > CH2SPh > CCl3 > C6Cl5 > CCPh ca.CCH.
