Check Digit Verification of cas no

The CAS Registry Mumber 72641-04-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,4 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 72641-04:
(7*7)+(6*2)+(5*6)+(4*4)+(3*1)+(2*0)+(1*4)=114
114 % 10 = 4
So 72641-04-4 is a valid CAS Registry Number.

Lanthanide replacement in organic synthesis: Luche-type reduction of α,β-unsaturated ketones in the presence of calcium triflate

Forkel, Nina V.,Henderson, David A.,Fuchter, Matthew J.

supporting information; scheme or table, p. 2129 - 2132 (2012/09/08)

Development of a calcium-mediated regioselective 1,2-reduction of challenging α,β-unsaturated ketones, such as 2-cyclopententone, is reported. The corresponding allylic alcohols are obtained in very good regioselectivities using Ca(OTf)2 and NaBH4. Furthermore, we have shown that our method can stereoselectively reduce aziridinyl ketones.

Reaction of Raney Nickel with Alcohols

Krafft, Marie E.,Crooks, William J.,Zorc, Branka,Milczanowski, Stephen E.

, p. 3158 - 3163 (2007/10/02)

The reaction of Raney nickel with a variety of functional groups was studied.Ethers, esters, and alkyl chlorides were found to be stable to Raney nickel in refluxing toluene; however, alcohols were found to be reactive.Primary alcohols were oxidized to aldehydes and the subsequently decarbonylated, secondary alcohols were oxidized to the corresponding ketone, and tertiary alcohols were deoxygenated.
