Check Digit Verification of cas no

The CAS Registry Mumber 27702-10-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,7,0 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 27702-10:
(7*2)+(6*7)+(5*7)+(4*0)+(3*2)+(2*1)+(1*0)=99
99 % 10 = 9
So 27702-10-9 is a valid CAS Registry Number.

INDIRECT ELECTROCHEMICAL SIDE-CHAIN OXIDATION OF ALKYL AROMATIC COMPOUNDS - SELECTIVE SYNTHESIS OF METHYL BENZOATES OR ORTHOBENZOIC ACID TRIMETHYLESTERS

Brinkhaus, Karl-Heinz Grosse,Steckhan, Eberhard,Degner, Dieter

, p. 553 - 560 (2007/10/02)

The technically important side-chain oxidation of alkyl aromatic compounds to form either methyl benzoates or orthobenzoic acid trimethylesters can be performed electrochemically at low potentials in methanol solution using an undivided cell and tris(2,4-dibromophenyl)amine as redox catalyst.Under neutral or slightly acidic conditions methyl benzoates are selectively formed while under basic conditions the orthoesters are predominating.In a similar way ortho benzoic acid trimethylesters are formed selectively starting from benzaldehyde dimethylacetals.The redox catalyst is stable under the reaction conditions so that several thousand cycles can be performed without noticeable loss.
