Check Digit Verification of cas no
The CAS Registry Mumber 557768-22-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,7,6 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 557768-22:
(8*5)+(7*5)+(6*7)+(5*7)+(4*6)+(3*8)+(2*2)+(1*2)=206
206 % 10 = 6
So 557768-22-6 is a valid CAS Registry Number.

Catalytic enantioselective desymmetrization of COT-monoepoxide. Maximum deviation from coplanarity for an SN2′-cuprate alkylation

(Matrix presented) The first alkylative and enantioselective ring-opening of COT-monoepoxide (1) without the occurrence of any ring-contraction-isomerization by the use of in situ-formed organocuprates is reported. Because of the particular geometric constraint of compound 1, this work reports the largest deviation from coplanarity between the π-orbital of the double bond and the σ-bond connecting the leaving group ever observed for an SN2′-cuprate alkylation.
