Check Digit Verification of cas no

The CAS Registry Mumber 457625-25-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,7,6,2 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 457625-25:
(8*4)+(7*5)+(6*7)+(5*6)+(4*2)+(3*5)+(2*2)+(1*5)=171
171 % 10 = 1
So 457625-25-1 is a valid CAS Registry Number.

Copper-catalyzed asymmetric ring opening of oxabicyclic alkenes with organolithium reagents

Bos, Pieter H.,Rudolph, Alena,Perez, Manuel,Fananas-Mastral, Martin,Harutyunyan, Syuzanna R.,Feringa, Ben L.

supporting information; experimental part, p. 1748 - 1750 (2012/03/09)

A highly efficient method is reported for the asymmetric ring opening of oxabicyclic alkenes with organolithium reagents. Using a copper/chiral phosphoramidite complex together with a Lewis acid (BF3· OEt2), full selectivity for the anti isomer and excellent enantioselectivities were obtained for the ring opened products.

Copper-catalyzed asymmetric ring opening of oxabicyclic alkenes with Grignard reagents

Zhang, Wei,Wang, Li-Xin,Shi, Wen-Jian,Zhou, Qi-Lin

, p. 3734 - 3736 (2007/10/03)

(Chemical Equation Presented) Simple Grignard reagents were applied in copper-catalyzed asymmetric ring-opening reactions of oxabenzonorbornadiene derivatives using spiro phosphoramidite ligands. Excellent anti- stereoselectivities and good enantioselecti

Copper phosphoramidite catalyzed enantioselective ring-opening of oxabicyclic alkenes: Remarkable reversal of stereocontrol

Bertozzi, Fabio,Pineschi, Mauro,Macchia, Franco,Arnold, Leggy A.,Minnaard, Adriaan J.,Feringa, Ben L.

, p. 2703 - 2705 (2007/10/03)

An unprecedented copper phosphoramidite catalyzed enantioselective alkylative ring-opening reaction of oxabenzonorbornadiene derivatives with dialkylzinc reagents is reported. The reaction shows high levels of anti-stereoselectivity (up to anti/syn >99:1), complementary to the Pd(0)-catalyzed syn-selective ring-opening protocol, allowing a new entry to anti-dihydronaphthols with high enantioselectivity (up to 99% ee).
