Check Digit Verification of cas no
The CAS Registry Mumber 158694-15-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,6,9 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 158694-15:
(8*1)+(7*5)+(6*8)+(5*6)+(4*9)+(3*4)+(2*1)+(1*5)=176
176 % 10 = 6
So 158694-15-6 is a valid CAS Registry Number.

Intramolecular Catalysis. Part 5. The Intramolecular Cannizzaro Reaction of o-Phthalaldehyde and -o-Phthalaldehyde
Bowden, Keith,El-Kaissi, Faiq A.,Ranson, Richard J.

o-Phthalaldehyde, as well as the α,α'-dideuterio isomer, has been shown to undergo Cannizzaro reaction in water containing base, while partially hydrated and ionised.The reaction of the monoanion of the hydrate is intramolecular and of first order in the monoanion of the hydrate, and either first or zero order in the base.The rate coefficients have been measured at several temperatures and activation parameters evaluated.The kinetic isotope effect, kH/k(2)H, for the first and second order processes were found to be ca 1.9 and 1.8, respectively.The alkaline hydroly sis of the corresponding lactone, phtalide, has also been studied under the same conditions.The evidence for the intramolecular Cannizzaro reaction indicates a mechanistic pathway involving rate-determining hydride transfer from the chain tautomers of both monoanion and dianion of the hydrate.
