Check Digit Verification of cas no

The CAS Registry Mumber 4646-99-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4646-99:
(6*4)+(5*6)+(4*4)+(3*6)+(2*9)+(1*9)=115
115 % 10 = 5
So 4646-99-5 is a valid CAS Registry Number.

From precursor to catalyst: The involvement of [Ru(η5- Cp*)Cl2]2 in highly branch selective allylic etherification of cinnamyl chlorides

Siddappa, Ravi Kumara Guralamatta,Chang, Chih-Wei,Chein, Rong-Jie

supporting information, p. 1031 - 1035 (2014/02/14)

(RuCp*Cl2)2, a general entry into Cp*Ru sandwich and half-sandwich chemistry was first used as a precatalyst in allylic etherification of cinnamyl chlorides with up to 98:2 regioselectivity (19 examples). Both the solvent effect and the exsiccant reaction condition are crucial to the reactivity and selectivity. Preliminary mechanism studies and the demonstration of Fluoxetine synthesis were presented in this work as well.
