Check Digit Verification of cas no
The CAS Registry Mumber 39557-39-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,5,5 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39557-39:
(7*3)+(6*9)+(5*5)+(4*5)+(3*7)+(2*3)+(1*9)=156
156 % 10 = 6
So 39557-39-6 is a valid CAS Registry Number.

Synthesis and Photochemistry of a New Class of Photocleavable Protein Cross-linking Reagents
Milanesi, Lilia,Reid, Gavin D.,Beddard, Godfrey S.,Hunter, Christopher A.,Waltho, Jonathan P.

A new series of photocleavable protein cross-linking reagents based on bis(maleimide) derivatives of diaryl disulfides have been synthesised. They have been functionalised with cysteine and transient absorption spectra for the photolysis reaction have been recorded by using the pump-probe technique with a time resolution of 100 femtoseconds. Photolysis of the disulfide bond yields the corresponding thiyl radicals in less than a picosecond. There is a significant amount of geminate recombination, but some of the radicals escape the solvent cage and the quantum yield for photocleavage is 30% in water.
