Check Digit Verification of cas no

The CAS Registry Mumber 24243-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,2,4 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 24243-17:
(7*2)+(6*4)+(5*2)+(4*4)+(3*3)+(2*1)+(1*7)=82
82 % 10 = 2
So 24243-17-2 is a valid CAS Registry Number.

Regioselective Functionalization of Non-Activated CH-bonds, 2. Photochemical Functionalization of the Myristoyl Group in 1,2-Alkanediyl and o-Phenylene 1-(4-Benzoylbenzoate) 2-Myristates

Dors, Bernhard,Luftmann, Heinrich,Schaefer, Hans J.

, p. 761 - 776 (2007/10/02)

Myristic acid (1a) was linked with ethylene glycol (2a), trans-1,2-cyclohexanediol (2b), and catechol (2c) to 4-benzoylbencoic acid to form the diesters 4a-c.These cyclize by photolysis to the carbinols 12, which are converted into the methyl 7- to 13-oxomyristates (5a).The ketofunctionalization of the remote CH2-groups in 1a is more selective than in the corresponding benzoylbenzoic esters 13 without the 1,2-alkanediyl or o-phenylene link.Additionally the maximum of the functionalization is shifted from the end towards the middle of the chain.The latter observation can be explained by a higher population of gauche conformations at the beginning of the chain.In CCl4 the selectivity increases slightly from 4a to 4b, c with increasing rigidity of the link.The polarity of the solvent has only a small effect on the selectivity.
