Check Digit Verification of cas no

The CAS Registry Mumber 345227-62-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,5,2,2 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 345227-62:
(8*3)+(7*4)+(6*5)+(5*2)+(4*2)+(3*7)+(2*6)+(1*2)=135
135 % 10 = 5
So 345227-62-5 is a valid CAS Registry Number.

The Conjugate Addition of a Silyl Group to Enones and its Removal with Copper(II) Bromide: A Protecting Group for the αβ-Unsaturation of αβ-Unsaturated Ketones

Ager, David J.,Fleming, Ian,Patel, Shailesh K.

, p. 2520 - 2526 (2007/10/02)

Silyl-lithium reagents mixed with copper(I) salts react with enones, including esters and aldehydes, to give β-silyl carbonyl compounds in good yield.The β-silylketones can be used in synthesis without risk to the silyl group and the enone group can be restored by bromination-desilylbromination with copper(II) bromide.The principle is illustrated with syntheses of carvone and dihydrojasmone.
