Check Digit Verification of cas no

The CAS Registry Mumber 51957-07-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,9,5 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51957-07:
(7*5)+(6*1)+(5*9)+(4*5)+(3*7)+(2*0)+(1*7)=134
134 % 10 = 4
So 51957-07-4 is a valid CAS Registry Number.

A bisazobenzene crosslinker that isomerizes with visible light

Samanta, Subhas,Qureshi, Harris I.,Woolley, G. Andrew

, p. 2184 - 2190 (2013/02/23)

Background: Large conformational and functional changes of azobenzene-modified biomolecules require longer azobenzene derivatives that undergo large end-to-end distance changes upon photoisomerization. In addition, isomerization that occurs with visible r
