858885-66-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 858885-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,8,8 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 858885-66:
(8*8)+(7*5)+(6*8)+(5*8)+(4*8)+(3*5)+(2*6)+(1*6)=252
252 % 10 = 2
So 858885-66-2 is a valid CAS Registry Number.

Synthesis of a library of chiral α-amino acid-based borate counteranions and their application to copper catalyzed olefin cyclopropanation

Llewellyn, David B.,Arndtsen, Bruce A.

, p. 1789 - 1799 (2005)

Twenty borate counteranions have been prepared from tartaric acid and α-amino acid derivatives. Ion pairing of these anions to a copper cation can be used to induce enantioselectivity into the copper catalyzed cyclopropanation of styrene. Structural modification of the anion provides insight into the importance of each component of the counteranion in asymmetric induction.
