Check Digit Verification of cas no

The CAS Registry Mumber 81445-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,4 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81445-52:
(7*8)+(6*1)+(5*4)+(4*4)+(3*5)+(2*5)+(1*2)=125
125 % 10 = 5
So 81445-52-5 is a valid CAS Registry Number.

Attempted Amplification of Optical Activity by Crystallization of Chiral Crystals of Photopolymerizing Dienes in the Presence of Their Topochemical Products

Mil, Jan van,Addadi, Lia,Gati, Edna,Lahav, Meir

, p. 3429 - 3434 (1982)

Monomeric dienes 1-7, which pack in chiral crystal structures and yield upon irradiation chiral dimers, trimers, and oligomers, have beeen crystallized in the presence of small amounts of their photoproducts ("impurities").An efficient asymmetric inductio
