77461-24-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77461-24-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,6 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77461-24:
(7*7)+(6*7)+(5*4)+(4*6)+(3*1)+(2*2)+(1*4)=146
146 % 10 = 6
So 77461-24-6 is a valid CAS Registry Number.

Total Synthesis of (+/-)-4'-Demethyl-4-epipodophyllotoxin by Insertion-Cyclization
Kende, Andrew S.,King, Margaret Logan,Curran, Dennis P.
, p. 2826 - 2828 (2007/10/02)
The total synthesis of (+/-)-4'-O-demethyl-4-epipodophyllotoxin (3) is accomplished in 13 steps and 2.4percent overall yield from piperonal through the use of an "insertion-cyclization" reaction to form the aryltetralin ring system.
