121190-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121190-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,9 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 121190-18:
(8*1)+(7*2)+(6*1)+(5*1)+(4*9)+(3*0)+(2*1)+(1*8)=79
79 % 10 = 9
So 121190-18-9 is a valid CAS Registry Number.

THERMAL O -> C REARRANGEMENT OF N-PHENYL-ALLYLIMIDATES
Metz, P.,Mues, C.
, p. 6841 - 6854 (2007/10/02)
Properly substituted N-phenyl-allylimidates 1 are shown to undergo preferential O -> C sigmatropic rearrangement on heating.The diastereoselectivity of this reaction resembles the one observed in ortho ester Claisen rearrangements.
