Check Digit Verification of cas no
The CAS Registry Mumber 157918-96-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,9,1 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157918-96:
(8*1)+(7*5)+(6*7)+(5*9)+(4*1)+(3*8)+(2*9)+(1*6)=182
182 % 10 = 2
So 157918-96-2 is a valid CAS Registry Number.

An asymmetric synthesis of isopodophyllotoxin
Pelter,Ward,Qianrong,Pis
, p. 909 - 920 (2007/10/02)
(-)-Isopodophyllotoxin has been synthesised by a route involving an asymmetric Diels Alder reaction between (5R)-menthyloxy-2(5II)-furanone and an arylisobenzofuran. Raney nickel reduction of the major adduct affords 10- menthyloxyisopicropodophyllin whic
