117211-85-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117211-85-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,2,1 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117211-85:
(8*1)+(7*1)+(6*7)+(5*2)+(4*1)+(3*1)+(2*8)+(1*5)=95
95 % 10 = 5
So 117211-85-5 is a valid CAS Registry Number.

Synthesis of new benzopyrans related to podophyllotoxin
Jurd
, p. 1349 - 1352 (2007/10/02)
Mannich bases of types 1 or 8, which are readily synthesized by condensation of 3,4-methylenedioxyphenol with aromatic aldehydes and pyrrolidine or piperazine, react with cyclic and acyclic β-diketones to yield benzopyrans. These benzopyrans are structurally similar to podophyllotoxin and like this drug some of the benzopyrans show in vivo anti-leukemic action in mice.
