Check Digit Verification of cas no

The CAS Registry Mumber 143866-49-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,6 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143866-49:
(8*1)+(7*4)+(6*3)+(5*8)+(4*6)+(3*6)+(2*4)+(1*9)=153
153 % 10 = 3
So 143866-49-3 is a valid CAS Registry Number.

Extremely powerful chiral auxiliaries: Enantiomeric [4+2] cycloadducts of 2-oxazolone and 9,10-dimethylanthracene

Kimura,Murata,Otsuka,Ishizuka,Haratake,Kunieda

, p. 4461 - 4464 (1992)

Enantiomeric [4+2] cycloadduct-based 2-oxazolidinones (3a and 4a), newly derived from 9,10-dimethylanthracene and 2-oxazolone, serve as the most effective Evans' auxiliaries so far developed in diastereoselective alkylations and Diels-Alder reactions.
