Check Digit Verification of cas no

The CAS Registry Mumber 24831-13-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,8,3 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 24831-13:
(7*2)+(6*4)+(5*8)+(4*3)+(3*1)+(2*1)+(1*3)=98
98 % 10 = 8
So 24831-13-8 is a valid CAS Registry Number.

A C2-chiral bis(amidinium) catalyst for a Diels-Alder reaction constituting the key step of the Quinkert-Dane estrone synthesis

Tsogoeva, Svetlana B.,Duerner, Gerd,Bolte, Michael,Goebel, Michael W.

, p. 1661 - 1664 (2003)

A novel C2-chiral bis(amidinium) salt 12 has been synthesised from 5-(tert-butyl)isophthalic acid. The hydrogenbond-mediated association of dienophiles 3a and 3b with the chiral host molecule 12 accelerates the Diels-Alder reactions with diene 2 by more than three orders of magnitude. In addition, enantioselective formation of the desired adducts is observed under catalysis with 12. Good ratios of 4a(b) + ent-4a(b)/5a(b) + ent-5a(b) from 1:10 to 1:22 were found in all reactions.
