Check Digit Verification of cas no

The CAS Registry Mumber 34895-49-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,9 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 34895-49:
(7*3)+(6*4)+(5*8)+(4*9)+(3*5)+(2*4)+(1*9)=153
153 % 10 = 3
So 34895-49-3 is a valid CAS Registry Number.

Thermal Rearrangements of 8-Methoxybicycloocta-2,4-diene and 8-Methoxybicyclooct-2-ene

Kirmse, Wolfgang,Kuehr, Rolf,Murawski, Hans-Ruediger,Scheidt, Friedrich,Ullrich, Vera

, p. 1272 - 1279 (2007/10/02)

The equilibria 2x 3e and 9x 11 of the title compounds reveal a slight influence of methoxy substituents on the stability of cyclopropane rings.Reactions which involve the distal cyclopropane bond - the butadienylcyclopropane rearrangement of 2 and the homo-1,5-H shift of 9 - are but modestly accelerated by methoxy groups.The vinylcyclopropane rearrangement 9x -> 10 confirms the strong methoxy effect on proximal cyclopropane bonds.
