135949-34-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135949-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,4 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 135949-34:
(8*1)+(7*3)+(6*5)+(5*9)+(4*4)+(3*9)+(2*3)+(1*4)=157
157 % 10 = 7
So 135949-34-7 is a valid CAS Registry Number.

Photo-Cleavable Cryptands: Synthesis and Structure
Warmuth, Ralf,Grell, Ernst,Lehn, Jean-Marie,Bats, Jan W.,Quinkert, Gerhard
, p. 671 - 681 (2007/10/02)
The four photo-cleavable ligands 1 - 4 of the macrobicyclic-cryptand type have been synthesized by introducing a photo-sensitive 2-nitrobenzyl- or 4,5-dimethoxy-2-nitrobenzyl-ether bond into one of the bridges.These compounds are expected to retain the se
