Check Digit Verification of cas no

The CAS Registry Mumber 1263143-03-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,1,4 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1263143-03:
(9*1)+(8*2)+(7*6)+(6*3)+(5*1)+(4*4)+(3*3)+(2*0)+(1*3)=118
118 % 10 = 8
So 1263143-03-8 is a valid CAS Registry Number.

Ladder-type P,S-bridged trans-stilbenes

Weymiens, Wannes,Zaal, Mark,Slootweg, J. Chris,Ehlers, Andreas W.,Lammertsma, Koop

experimental part, p. 8516 - 8523 (2011/10/12)

Phosphole-containing π-systems have emerged as building blocks with enormous potential as electronic materials because of the tunability of the phosphorus center. Among these, asymmetric P-bridged trans-stilbenes are still rare, and here an elegant and ef
