129393-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129393-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,9 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129393-75:
(8*1)+(7*2)+(6*9)+(5*3)+(4*9)+(3*3)+(2*7)+(1*5)=155
155 % 10 = 5
So 129393-75-5 is a valid CAS Registry Number.

73Ge NMR spectra of 2-thienyl-, 2-furyl- and 2-(4,5-dihydrofuryl)germanes
Liepins, E.,Zicmane, I.,Ignatovich, L. M.,Lukevics, E.
, p. 23 - 28 (2007/10/02)
The 73Ge NMR spectra of 2-thiennyl, 2-furyl- and 2-(4,5-dihydrofuryl)germanes have been studied.The comparison of 73Ge chemical shifts with those of 29Si and 119Sn in isostructural silicon and tin derivatives confirms the existence of additional effects i
