Check Digit Verification of cas no

The CAS Registry Mumber 18402-58-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,0 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18402-58:
(7*1)+(6*8)+(5*4)+(4*0)+(3*2)+(2*5)+(1*8)=99
99 % 10 = 9
So 18402-58-9 is a valid CAS Registry Number.

Silylations of α,β-unsaturated and aromatic carbonyl compounds with cobalt carbonyls

Sisak, Attila

, p. 48 - 53 (2007/10/03)

[η3-η5-(Silyloxy-alkenyl)]-cobalt carbonyls and various silyl ethers were formed in the cobalt carbonyl mediated silylations of α,β-unsaturated and aromatic carbonyl compounds. A silyloxonium tetracarbonylcobaltate tight ion pair was suggested as a common intermediate, which provides the products through a radical pair in the cases of aromatic aldehydes and ketones.
