Check Digit Verification of cas no

The CAS Registry Mumber 34874-34-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,7 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 34874-34:
(7*3)+(6*4)+(5*8)+(4*7)+(3*4)+(2*3)+(1*4)=135
135 % 10 = 5
So 34874-34-5 is a valid CAS Registry Number.

On the Importance of Indiscriminate Insertion for Photoactivable Reagents - Photolysis of Diazofluorene in Mixed Organic Solvents

Anjaneyulu, P. S. R.,Lala, Anil K.

, p. 802 - 807 (2007/10/02)

Photolysis of diazofluorene (I), a new fluorescent photoactivable reagent, in cyclohexane, cyclohexene, methanol and in mixtures of the solvents is reported.Quantitative analysis of products formed has been carried out.In bulk hydrophobic milieu diazofluorene does show some indiscriminateness in its insertion reactions.The importance of indiscriminate insertion in photoaffinity labeling studies has been dicussed.A simple method has thus been developed to test the indiscriminate properties of a photoactivable reagent by photolysing it first in simple organic solvents.Such studies should prove useful and photoactivable reagents can be tested before applying them directly to biological systems.
