129840-70-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129840-70-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,4 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129840-70:
(8*1)+(7*2)+(6*9)+(5*8)+(4*4)+(3*0)+(2*7)+(1*0)=146
146 % 10 = 6
So 129840-70-6 is a valid CAS Registry Number.

The enigmatic 1J(CH) coupling constants of allyl-type organometallic compounds
Schlosser, Manfred,Lehmann, Ruth,Jenny, Titus
, p. 149 - 157 (2007/10/02)
A new attempt has been made to identify the factors responsible for the abnormally small one-bond C, H coupling constants observed for allyl, pentadienyl and heptatrienylmetal compounds.In-plane deformations (widening of the central CCC angle) should have
