Check Digit Verification of cas no
The CAS Registry Mumber 42981-76-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,9,8 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 42981-76:
(7*4)+(6*2)+(5*9)+(4*8)+(3*1)+(2*7)+(1*6)=140
140 % 10 = 0
So 42981-76-0 is a valid CAS Registry Number.

Influence of Ring Size on Geminal Interproton Coupling Constants in Exocyclic Methylene Groups
Spear, Robert J.,Sternhell, Sever
, p. 889 - 897 (2007/10/02)
In systems where substituent effects are constant, there is a well defined trend in the magnitude of geminal interproton coupling constants in exocyclic methylene groups with ring size.Reduction of ring size from six to five to four results in a monotonic reduction in the magnitude of Jgem.These trends apply to methylenecycloalkanes, methylenebenzocycloalkenes and α-methylenecycloalkanones.There is an indication that the trend does not continue for methylenecyclopropanes.A number of new exocyclic-methylene compounds have been designed and synthesized to provide specific experimental data.
