Check Digit Verification of cas no

The CAS Registry Mumber 33224-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,2 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33224-64:
(7*3)+(6*3)+(5*2)+(4*2)+(3*4)+(2*6)+(1*4)=85
85 % 10 = 5
So 33224-64-5 is a valid CAS Registry Number.

Photocatalytic hydrogenation of acetophenone derivatives and diaryl ketones on polycrystalline titanium dioxide

Kohtani, Shigeru,Yoshioka, Eito,Saito, Kenji,Kudo, Akihiko,Miyabe, Hideto

experimental part, p. 1049 - 1053 (2010/11/24)

In the absence of molecular oxygen, various aromatic ketones such as acetophenone derivatives and diaryl ketones were photocatalytically hydrogenated on polycrystalline titanium dioxide (Degussa P25) under UV light irradiation (> 340 nm). The desired secondary alcohols were obtained with excellent chemical efficiency (almost 100% yields for 10 examples) by choosing ethanol as a sacrificial hole scavenger, which was oxidized into acetaldehyde.
