77821-01-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77821-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,2 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77821-01:
(7*7)+(6*7)+(5*8)+(4*2)+(3*1)+(2*0)+(1*1)=143
143 % 10 = 3
So 77821-01-3 is a valid CAS Registry Number.

A NOVEL SYNTHESIS OF DIBENZO-1-AZABICYCLONONANES
Hara, Hiroshi,Hoshino, Osamu,Umezawa, Bunsuke
, p. 907 - 910 (2007/10/02)
Treatment of the N-benzylated p-quinol acetates (1a and 1b) with trifluoroacetic acid gave (+/-)-3-hydroxydibenzoazabicyclononanes (5a and 5c) in good yields.On the other hand, lead tetraacetate oxidation of 2-benzyl-6-hydroxy-7-methoxy-1,2,3,4-tetrahydro
