Check Digit Verification of cas no

The CAS Registry Mumber 77461-25-7 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 77461-25:
(7*7)+(6*7)+(5*4)+(4*6)+(3*1)+(2*2)+(1*5)=147
147 % 10 = 7
So 77461-25-7 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.
