90301-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90301-87-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,0 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90301-87:
(7*9)+(6*0)+(5*3)+(4*0)+(3*1)+(2*8)+(1*7)=104
104 % 10 = 4
So 90301-87-4 is a valid CAS Registry Number.

SYNTHESIS OF 4a-, 4e-PHENYLADAMANTANONES AND 2,4-o-BENZENOADAMANTANE BY Π-ROUTE
Hoffmann, Guenter Georg,Klein, Harald
, p. 199 - 202 (1984)
The acid catalysed reaction of 4-oxa-homoadamantan-5-one (1) with benzene yielded a mixture of 4a-phenyladamantan-2-one (7), the equatorial isomer (8) and 2-phenyl-2,4-o-benzenoadamantane (9).A plausible reaction pathway for the occurence of 9
