Check Digit Verification of cas no
The CAS Registry Mumber 37398-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,3,9 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 37398-49:
(7*3)+(6*7)+(5*3)+(4*9)+(3*8)+(2*4)+(1*9)=155
155 % 10 = 5
So 37398-49-5 is a valid CAS Registry Number.

Substituent Effects on Photochemical Hydrogen Abstraction in 2-Acylpyridines, 2-Acylpyrazines, and 4-Acylpyrimidines

Stern-Volmer quenching of the photochemistry of 1c indicates that N- and O-abstraction (eqs 1 and 2, respectively) are quenched at different rates (Figure 1).For quenching of 2c kqτ is 157 M-1 and for 3c, 64 M-1.When 1c is sensitized with triplet sensitizers of increasing ET,N-abstraction increases (Table 1).These data indicate that N- and O-abstraction in 1c take place from distiguishable triplet states.Survey of Φp's of ring-substituted ketones 1b-d, 6d, 7a,b,d, 8b, 9b,d, 10b, and 11d demonstartes the effect of substitution on the competition between N- and O-abstraction (Table 2).For methyl- and dicyano-substituted ketones, the results can be understood simply in terms of shifts in ET of the n?* and ??* states of the heterocycle.The photochemistry of all these ketones requires consideration of interactions among three triplet states.
