Check Digit Verification of cas no

The CAS Registry Mumber 133205-53-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,0 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133205-53:
(8*1)+(7*3)+(6*3)+(5*2)+(4*0)+(3*5)+(2*5)+(1*3)=85
85 % 10 = 5
So 133205-53-5 is a valid CAS Registry Number.

Synthesis and reactivity of allyl samarium complexes

Collin,Bied,Kagan

, p. 629 - 630 (2007/10/02)

Allyl chlorides react with SmCp2 to afford an allyl samarium intermediate, the η3-allyl structure of which has been tentatively assigned upon its reactivity with ketones. Synthesis of β,γ-unsaturated ketones have been also performed by reacting allyl samarium compounds with acid chlorides.
