Check Digit Verification of cas no

The CAS Registry Mumber 13004-07-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,0 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13004-07:
(7*1)+(6*3)+(5*0)+(4*0)+(3*4)+(2*0)+(1*7)=44
44 % 10 = 4
So 13004-07-4 is a valid CAS Registry Number.

Directed metal (oxo) aliphatic C-H hydroxylations: Overriding substrate bias

Bigi, Marinus A.,Reed, Sean A.,White, M. Christina

, p. 9721 - 9726 (2012/07/14)

The first general strategy for a directing effect on metal (oxo)-promoted C-H hydroxylations is described. Carboxylic acid moieties on the substrate overcome unfavorable electronic, steric, and stereoelectronic biases in C-H hydroxylations catalyzed by the non-heme iron complex Fe(PDP). In a demonstration of the power of this directing effect, C-H oxidation is diverted away from an electronically favored C-1 H abstraction/rearrangement pathway in the paclitaxel framework to enable installation of C-2 oxidation in the naturally occurring oxidation state and stereoconfiguration.
