Check Digit Verification of cas no

The CAS Registry Mumber 937025-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,7,0,2 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 937025-89:
(8*9)+(7*3)+(6*7)+(5*0)+(4*2)+(3*5)+(2*8)+(1*9)=183
183 % 10 = 3
So 937025-89-3 is a valid CAS Registry Number.

Tethered aminohydroxylation: Dramatic improvements to the process

Donohoe, Timothy J.,Bataille, Carole J. R.,Gattrell, William,Kloesges, Johannes,Rossignol, Emilie

, p. 1725 - 1728 (2008/02/02)

Changing the identity of the N leaving group on a hydroxylamine-based reoxidant gives a dramatic improvement to the tethered aminohydroxylation reaction. Using OCOC6F5 as a leaving group means that only 1 mol % of osmium is required and yields as high as 98% can be obtained. Acyclic homoallylic alcohols were substrates considered too unreactive for effective use in the tethered aminohydroxylation reaction; improved reaction conditions mean that they have now become viable substrates for oxidation.
