77131-00-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77131-00-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,3 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77131-00:
(7*7)+(6*7)+(5*1)+(4*3)+(3*1)+(2*0)+(1*0)=111
111 % 10 = 1
So 77131-00-1 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 (2007/10/02)
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
