Check Digit Verification of cas no

The CAS Registry Mumber 649767-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,7,6 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 649767-55:
(8*6)+(7*4)+(6*9)+(5*7)+(4*6)+(3*7)+(2*5)+(1*5)=225
225 % 10 = 5
So 649767-55-5 is a valid CAS Registry Number.

Photo-irradiation of α-halo carbonyl compounds: A novel synthesis of α-hydroxy- and α,α′-dihydroxyketones

Chai, Wen,Takeda, Akihiro,Hara, Makoto,Ji, Shun-Jun,Horiuchi, C. Akira

, p. 2453 - 2463 (2007/10/03)

The reaction of α-halo ketones (α-iodocycloalkanones, α-bromocycloalkanones, α-iodo-β-alkoxy esters, and α-iodoacyclicketones) with irradiation under a high-pressure mercury lamp gave the corresponding α-hydroxyketones in good yields. For α-bromoketones, it was found that α-hydroxylation does not occur. However, α-bromoketones were converted into α-hydroxyketones in the presence of KI. In the case of α,α′-diiodo ketones, α,α′-dihydroxyketones, which up to now have scarcely been reported, were obtained. This reaction affords a new, clean and convenient synthetic method for α-hydroxy- and α,α′- dihydroxyketones.
