Calculate Digit Verification of CAS Registry Number 53312-55:
(7*5)+(6*3)+(5*3)+(4*1)+(3*2)+(2*5)+(1*5)=93
93 % 10 = 3
So 53312-55-3 is a valid CAS Registry Number.

Base-catalysed rearrangement of p-menth-1-en-4(8)-oxide

Roy, Animesh,Gurudutt, K. N.,Rao, Sanjay

, p. 636 - 638 (2007/10/03)

p-Menth-1-en-4(8)-oxide (1), a tetrasubstituted spiro epoxide is normally resistant towards bases but under forcing condition with AIP rearranges to p-mentha-1,8-dien-4-ol (2).On the other hand, with t-BuOK, p-mentha-1,3-dien-8-ol (3) and p-mentha-1,4-dien-8-ol (4) are formed as the major products.These compounds readily get oxidised to p-cymen-8-ol (5), as seen in the reaction of 1 with N-LiEDA.
