Check Digit Verification of cas no

The CAS Registry Mumber 1374568-09-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,5,6 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1374568-09:
(9*1)+(8*3)+(7*7)+(6*4)+(5*5)+(4*6)+(3*8)+(2*0)+(1*9)=188
188 % 10 = 8
So 1374568-09-8 is a valid CAS Registry Number.

Oxidative homologation of aldehydes to α-ketoaldehydes by using iodoform, o-iodoxybenzoic acid, and dimethyl sulfoxide

Zall, Andrea,Bensinger, Dennis,Schmidt, Boris

experimental part, p. 1439 - 1447 (2012/04/04)

An efficient three-step synthetic route to α-ketoaldehydes starting from aryl aldehydes is reported. The aldehydes were treated with iPrMgCl and iodoform to obtain β-diiodoalcohols, which were then oxidized with o-iodoxybenzoic acid at room temperature to the corresponding β-diiodoketones. Subsequent reaction of the β-diiodoketone to the α-ketoaldehyde occurred under oxygen transfer from dimethyl sulfoxide. These sensitive products were in situ cyclized with o-phenylenediamine to form the stable monosubstituted quinoxalines, which could be characterized and isolated easily. α-Ketoaldehydes are a versatile, highly reactive moiety for the synthesis of heterocyclic compounds. We investigated the transformation of aldehydes into α-ketoaldehydes via β-diiodoketone intermediates and finally applied the procedure to the synthesis of peptidic substrates. Copyright
